Handle more _FloatN, _FloatNx types in include/float.h.
Continuing the preparation for additional _FloatN / _FloatNx type support, this patch adds support in include/float.h. This header defines macros for _Float128 properties when using compilers before GCC 7 that lack those macros in <float.h>. For testing _Float32 / _Float64 / _Float32x / _Float64x functions with older compilers, such macros need to be defined for those types as well; for the older compilers, those types will always be typedefs for another type, so the definitions can be in terms of the macros for that other type. Tested for x86_64. * include/float.h [!__GNUC_PREREQ (7, 0) && __GLIBC_USE (IEC_60559_TYPES_EXT) && __HAVE_FLOAT32] (FLT32_MANT_DIG): New macro.
