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.
