Move SNAN_TESTS_TYPE_CAST out of math-tests.h.
The math-tests.h header has many different macros and groups of
macros, defined using #ifndef in the generic version which is included
by architecture versions with #include_next after possibly defining
non-default versions of some of those macros.
This use of #ifndef is contrary to our normal typo-proof conventions
for macro definitions. This patch moves one of the macros,
SNAN_TESTS_TYPE_CAST, out to its own sysdeps header, to follow those
typo-proof conventions more closely.
Tested with build-many-glibcs.py.

* sysdeps/generic/math-tests-snan-cast.h: New file.
* sysdeps/powerpc/math-tests-snan-cast.h: Likewise.
* sysdeps/generic/math-tests.h: Include <math-tests-snan-cast.h>.
(SNAN_TESTS_TYPE_CAST): Do not define macro here.
* sysdeps/powerpc/math-tests.h (SNAN_TESTS_TYPE_CAST): Likewise.
