Remove the finite-math tests from the testsuite - these are no longer
useful after removing math-finite.h header.
Passes buildmanyglibc, build&test on x86_64 and AArch64.

This patch continues preparations for adding TS 18661-1 narrowing libm
functions by adding the required testsuite infrastructure to test such
functions through the libm-test infrastructure.
That infrastructure is based around testing for a single type, FLOAT.
For the narrowing functions, FLOAT, the "main" type for testing, is
the function return type; the argument type is ARG_FLOAT. This is
consistent with how the code built once for each type,
libm-test-support.c, depends on FLOAT for such things as calculating
ulps errors in results but can already handle different argument types
(pointers, integers, long double for nexttoward).
Makefile machinery is added to handle building tests for all pairs of
types for which there are narrowing functions (as with non-narrowing
functions, aliases are tested just the same as the functions they
alias). gen-auto-libm-tests gains a --narrow option for building
outputs for narrowing functions (so narrowing sqrt and fma will share
the same inputs as non-narrowing, but gen-auto-libm-tests will be run
with and without that option to generate different output files). In
the narrowing case, the auto-libm-test-out-narrow-* files include
annotations for each test about what properties ARG_FLOAT must have to
be able to represent all the inputs for that test; those annotations
result in calls to the TEST_COND_arg_fmt macro.
gen-libm-test.pl has some minor updates to handle narrowing tests (for
example, arguments in such tests must be surrounded by ARG_LIT calls
instead of LIT calls). Various new macros are added to the C test
support code (for example, sNaN initializers need to be properly
typed, so arg_snan_value is added; other such arg_* macros are added
as it seems cleanest to do so, though some are not strictly required).
Special-casing of the ibm128 format to allow for its limitations is
adjusted to handle it as the argument format as well as as the result
format; thus, the tests of the new functions allow nonzero ulps only
in the case where ibm128 is the argument format, as otherwise the
functions correspond to fully-defined IEEE operations. The ulps in
question appear as e.g. 'Function: "add_ldouble"' in libm-test-ulps
(with 1ulp errors then listed for double and float for that function
in powerpc); no support is added to generate corresponding faddl /
daddl ulps listings in the ulps table in the manual.
For the previous patch, I noted the need to avoid spurious macro
expansions of identifiers such as "add". A test test-narrow-macros.c
is added to verify such macro expansions are successfully avoided, and
there is also a -mlong-double-64 version of that test for ldbl-opt.
This test is set up to cover the full set of relevant identifiers from
the start rather than adding functions one at a time as each function
group is added.
Tested for x86_64 (this patch in isolation, as well as testing for
various configurations in conjunction with the actual addition of
"add" functions).

At present, libm tests for each function get built into a single
executable (for each floating point type, for each of normal / inline
/ finite-math-only functions, plus vector variants) and run together,
resulting in a single PASS or FAIL (for each of those nine variants
plus vector variants). Building this executable involves reading
over 50 MB of libm-test-*.c sources.
This patch arranges for tests of each function to be run separately
from the makefiles instead. There are 121 functions being tested for
each (type, variant pair) (actually 126, but run as 121 from the
Makefile because each of the pairs (exp10, pow10), (isfinite, finite),
(lgamma, gamma), (remainder, drem), (scalbn, ldexp), shares a table of
test results and so is run together), so 1089 separate tests run from
the Makefile, plus 48 vector tests on x86_64 (six functions for eight
vector variants). Each test only involves a libm-test-<func>.c file
of no more than about 4 MB, rather than all such files taking about 50
MB. With tests run separately, test summaries will indicate which
functions actually have problems (of course, those problems may just
be out-of-date libm-test-ulps files if the file hasn't been updated
for the architecture in question recently).
All the .c files for the 1089+48 tests are generated automatically
from the Makefiles. Various checked-in boilerplate .c files are
removed as no longer needed. CFLAGS definitions for the different
kinds of tests are generated using makefile iterators to apply
target-specific variable settings. libm-have-vector-test.h is no
longer needed; the list of functions to test for each vector type is
now in the sysdeps Makefile.
This should reduce the amount of boilerplate needed for float128
testing support; test-float128.h will still be needed, but not various
.c files or Makefile CFLAGS definitions. The logic for creating
dependencies on libm-test-support-*.o files should also render
<https://sourceware.org/ml/libc-alpha/2017-02/msg00279.html>
unnecessary.
Tested for x86_64 and x86.

The libm vector tests disable tests of exception raising via defining
macros EXCEPTION_TESTS_float and EXCEPTION_TESTS_double to 0 in the
headers for individual vector lengths.
As EXCEPTION_TESTS is used in code in libm-test-driver.c that is
otherwise ready to be built only once per type, this is not a good
idea; it's better to define TEST_EXCEPTIONS appropriately so that
flag_test_exceptions then gets initialized appropriately.
Furthermore, it's better to do this just once, in test-math-vector.h,
since there is no actual dependence on the vector length or type.
This patch duly makes that change.

This patch arranges for the libm-test tests to be run for the
finite-math-only function variants, in addition to the existing runs
for out-of-line and bits/mathinline.h inline variants.
gen-libm-test.pl is made to add a flag to all tests with non-finite
inputs or outputs so that they can be skipped at runtime when the
finite-math-only variants are being tested (skipping is for all
rounding modes; that is, -ffinite-math-only is being treated as
excluding overflow cases even when the rounding mode is such that the
overflowed result is finite). errno setting is not tested for these
variants (in general they don't set it, and it's
implementation-defined in ISO C whether it's set on underflow, with
the glibc definition being that it may not be for -ffinite-math-only;
other cases where errno would normally be expected to be set are
mostly excluded as having non-finite or overflowing arguments or
results).
As with the inline function tests, these ones are built with
-D__FINITE_MATH_ONLY=1 to select the function variants, rather than
-ffinite-math-only. Use of -ffinite-math-only would not be suitable
for these tests because it would also affect libm-test.inc code that
e.g. tests whether results are infinities or NaNs - if these function
variants have bugs that incorrectly produce such results, we want them
to show up in the tests, which means the compiler should not be
optimizing the tests on the basis of results being finite.
The finite-math-only functions share the same ulps settings as the
main out-of-line functions.
These interfaces were one significant group of untested ABIs listed at
<https://sourceware.org/ml/libc-alpha/2013-07/msg00386.html>. I
haven't rerun the script to list untested interfaces, but I expect
that the vast bulk of interfaces there are still untested and could do
with testcases being added (or, if applicable, being made compat
symbols; in general, most symbols not starting '_' are safe bets to
add tests for, while _* need more investigation of what the actual
public API is, if any). I'd like to encourage people to help reduce
the accumulation of untested interfaces by adding more tests.
Tested for x86_64 and x86. Given my recent lgamma/gamma and log*
fixes, the new tests pass (before those fixes, the new tests showed up
those bugs, so illustrating the practical utility of having tests for
these function variants).

This patch refactors how libm-test.inc handles disabling
errno/exception handling tests, and some other tests, for
__FAST_MATH__ inline function tests.
The macro TEST_INLINE is changed from being defined/undefined to being
defined to 1 or 0, so that it can be tested in "if" conditionals
instead of #if. For tests of errno and exception setting, separate
macros TEST_ERRNO and TEST_EXCEPTIONS are added, and TEST_ERRNO is
also used in the disabling of errno testing for vector function
tests. The relevant conditionals are moved up a function, so that
they take effect before the code that counts the number of tests, so
the inline function tests now accurately report that 0 tests for
exceptions and errno were executed (whereas they previously reported a
large number desipte not running any such tests).
Tested for x86_64 and x86.

This patch refactors the libm tests using libm-test.inc to reduce the
level of duplicate definitions. New headers are created for the
definitions shared by tests for a particular type; by tests of inline
functions; by tests of non-inline functions; by scalar tests; and by
vector tests. The unused MATHCONST macro is removed. A new macro
VEC_LEN is added to the vector headers to allow the macros defining
wrappers for vector functions to be defined once, instead of six times
each (differing only in vector length) as before. There is still
scope for further refactoring, but this seems a useful start.
