Move SNAN_TESTS_* out of math-tests.h.
Continuing moving macros out of math-tests.h to smaller headers following typo-proof conventions instead of using #ifndef, this patch moves the SNAN_TESTS_* macros for individual types out to their own sysdeps header (while the type-generic SNAN_TESTS wrapper for those macros remains in math-tests.h). Tested for x86_64 and x86, and with build-many-glibcs.py. * sysdeps/generic/math-tests-snan.h: New file. * sysdeps/generic/math-tests.h: Include <math-tests-snan.h>. (SNAN_TESTS_float): Do not define here. (SNAN_TESTS_double): Likewise. (SNAN_TESTS_long_double): Likewise. (SNAN_TESTS_float128): Likewise. * sysdeps/i386/fpu/math-tests-snan.h: New file. * sysdeps/i386/fpu/math-tests.h: Remove file. * sysdeps/ia64/math-tests-snan.h: New file. * sysdeps/ia64/math-tests.h: Remove file. * sysdeps/x86/math-tests.h: Likewise. * sysdeps/x86_64/fpu/math-tests-snan.h: New file.
