Macroize inclusion of math-finite.h
This patch macroizes the declarations in math/bits/math-finite.h similarly to what math/bits/mathcalls.h does. For each floating-point type, the file is included once in math/math.h. This will reduce the amount of repetitive boilerplate required when adding float128 versions of these declarations. Tested for powerpc64le and s390x. * math/math.h: Include bits/math-finite.h once per floating-point type. * math/bits/math-finite.h: Macroize all declarations by floating-point type.
