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.
