This patch makes math-tests.h, as used to describe support of given floating-point types for sNaNs, rounding modes and exceptions, handle distinguishing _Float128 from long double. This is needed for x86_64, where if building with GCC 6 or earlier there is no __builtin_nansq, so no way to get a signaling NaN of _Float128 type, so associated tests cannot be run (although glibc itself works fine, as there is never any need to create such an sNaN with a built-in function inside glibc). Tested for x86_64 (in conjunction with float128 patches). * sysdeps/generic/math-tests.h: Include <bits/floatn.h>. (MATH_TESTS_TG): New macro. (SNAN_TESTS_float128): Likewise. (ROUNDING_TESTS_float128): Likewise. (EXCEPTION_TESTS_float128): Likewise. (SNAN_TESTS): Define using MATH_TESTS_TG. (ROUNDING_TESTS): Likewise. (EXCEPTION_TESTS): Likewise.
