Refactor libm tests.

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.

Tested for x86_64.
