Gabriel F. T. Gomes a16e8bc08e Provide a C++ version of issignaling that does not use __MATH_TG
The macro __MATH_TG contains the logic to select between long double and
_Float128, when these types are ABI-distinct.  This logic relies on
__builtin_types_compatible_p, which is not available in C++ mode.

On the other hand, C++ function overloading provides the means to
distinguish between the floating-point types.  The overloading
resolution will match the correct parameter regardless of type
qualifiers, i.e.: const and volatile.

Tested for powerpc64le, s390x, and x86_64.

	* math/math.h [defined __cplusplus] (issignaling): Provide a C++
	definition for issignaling that does not rely on __MATH_TG,
	since __MATH_TG uses __builtin_types_compatible_p, which is only
	available in C mode.
	(CFLAGS-test-math-issignaling.cc): New variable.
	* math/Makefile [CXX] (tests): Add test-math-issignaling.
	* math/test-math-issignaling.cc: New test for C++ implementation
	of type-generic issignaling.
	* sysdeps/powerpc/powerpc64le/Makefile [subdir == math]
	(CXXFLAGS-test-math-issignaling.cc): Add -mfloat128 to the build
	options of test-math-issignaling on powerpc64le.
