Move float128 inlines from sysdeps/generic/math_private.h to include/math.h.
Continuing the cleanup of math_private.h, with a view to it becoming the header for the APIs defined therein and not also a header with inline variants of math.h APIs, this patch moves inline definitions of __isinff128 and fabsf128 to include/math.h, so that any users of math.h in glibc automatically get the optimized functions rather than quietly missing them if they do not also include math_private.h. Tested for x86_64 and x86, and with build-many-glibcs.py with GCC 6. There are changes to installed stripped libc.so on configurations with distinct _Float128, because of __printf_fp_l code that now gets the __isinff128 inline where previously it called the out-of-line function because of the lack of a math_private.h call. It seems appropriate that this code does get the inline (as it would automatically with GCC 7 and later when the built-in function is used) rather than being the only place in glibc that does not. * sysdeps/generic/math_private.h [__HAVE_DISTINCT_FLOAT128 && !__GNUC_PREREQ (7, 0)] (__isinff128): Move this inline function .... [__HAVE_DISTINCT_FLOAT128] (fabsf128): And this one .... * include/math.h [!_ISOMAC]: To here....
