As noted in bug 21607, NO_LONG_DOUBLE conditionals in libm tests are
no longer effective. For most this is harmless - they were only
present because of long double functions not being declared with _LIBC
defined, and _LIBC is no longer defined for building most tests. For
the few where this is actually relevant to the test, testing
LDBL_MANT_DIG > DBL_MANT_DIG is more appropriate as that limits the
test to public APIs. This patch fixes the tests accordingly.
Tested for x86_64 and arm.

The test math/test-nearbyint-except conditions some of its tests on an
EXCEPTION_TESTS call, not not all that need such a condition. This
patch fixes it to use such a conditional for all its tests and to
return 77 (UNSUPPORTED) if none of the floating-point types tested
support exceptions.
Tested for mips64 soft float (where the test previously failed and is
now UNSUPPORTED); also tested for x86_64 to make sure the test still
PASSes in exceptions-supported cases.
* math/test-nearbyint-except.c: Include <stdbool.h>.
(any_supported): New variable.
(TEST_FUNC): Return early if !EXCEPTION_TESTS (FLOAT). Otherwise
set any_supported.
(do_test): Return 77 if no floating-point type supported
exceptions.

The implementations of nearbyint functions using x87 floating point
(i386 all versions, x86_64 long double only) use the fclex
instruction, which clears any exceptions that were raised before the
function was called. These functions must not clear exceptions that
were raised before they were called.
This patch fixes these functions to save and restore the whole
floating-point environment (fnstenv / fldenv) as the way of avoiding
raising "inexact" (recall that there isn't an x87 instruction for
loading just the status word, so the whole environment has to be saved
and loaded instead - the code already saved and loaded the control
word, which is now obtained from the saved environment after this
patch, to disable traps on "inexact"). In the case of the long double
functions, any "invalid" exception from frndint (applied to a
signaling NaN) needs merging into the saved state; this issue doesn't
apply to the float and double functions because that exception would
have been raised when the argument is loaded, before the environment
is saved.
[BZ #15491]
* sysdeps/i386/fpu/s_nearbyint.S (__nearbyint): Save and restore
floating-point environment instead of clearing all exceptions.
* sysdeps/i386/fpu/s_nearbyintf.S (__nearbyintf): Likewise.
* sysdeps/i386/fpu/s_nearbyintl.S (__nearbyintl): Likewise,
merging in "invalid" exceptions from frndint.
* sysdeps/x86_64/fpu/s_nearbyintl.S (__nearbyintl): Likewise.
* math/test-nearbyint-except.c: New file.
* math/Makefile (tests): Add test-nearbyint-except.
