Remove x86 mathinline.h asinh, acosh, atanh inlines.
Continuing the removal of bits/mathinline.h inlines that would better be done by the compiler, this patch removes x86 inlines for asinh, acosh and atanh functions (only for fast-math, non-SSE 32-bit x86). I've filed <https://gcc.gnu.org/bugzilla/show_bug.cgi?id=88502> for adding such inlines as an optimization in GCC. Tested for x86_64 and x86. * sysdeps/x86/fpu/bits/mathinline.h (asinh): Remove inline definition. (acosh): Likewise. (atanh): Likewise.
