Remove x86 mathinline.h hypot inline. 

Continuing the removal of bits/mathinline.h inlines that would better
be done by the compiler, this patch removes an x86 inline for hypot
functions (only for fast-math, only for non-SSE 32-bit x86).  I've
filed <https://gcc.gnu.org/bugzilla/show_bug.cgi?id=88474> for adding
such an inline as an optimization in GCC.

Tested for x86_64 and x86.

	* sysdeps/x86/fpu/bits/mathinline.h (hypot): Remove inline
	definition.
