Include bits/math-finite.h for more _FloatN, _FloatNx types.
Continuing the preparation for additional _FloatN / _FloatNx type
support, this patch extends the includes of <bits/math-finite.h> to
cover all such types, under conditions analogous to those for
_Float128.

Tested for x86_64.

	* math/math.h [__HAVE_DISTINCT_FLOAT16 || (__HAVE_FLOAT16 && !_LIBC)]:
	Include <bits/math-finite.h> with appropriate macros defined and
	undefined.
	[__HAVE_DISTINCT_FLOAT32 || (__HAVE_FLOAT32 && !_LIBC)]: Likewise.
	[__HAVE_DISTINCT_FLOAT64 || (__HAVE_FLOAT64 && !_LIBC)]: Likewise.
	[__HAVE_DISTINCT_FLOAT32X || (__HAVE_FLOAT32X && !_LIBC)]: Likewise.
	[__HAVE_DISTINCT_FLOAT64X || (__HAVE_FLOAT64X && !_LIBC)]: Likewise.
	[__HAVE_DISTINCT_FLOAT128X || (__HAVE_FLOAT128X && !_LIBC)]: Likewise.
