694aabefd2 Simplify hypotf infinity handling (bug 15918).
Bug 15918 points out that the handling of infinities in hypotf can be
simplified: it's enough to return the absolute value of the infinite
argument without first comparing it to the other argument and possibly
returning that other argument's absolute value.  This patch makes that
cleanup (which should not change how hypotf behaves on any input).

Tested for x86_64.

	[BZ #15918]
	* sysdeps/ieee754/flt-32/e_hypotf.c (__ieee754_hypotf): Simplify
	handling of cases where one argument is an infinity.

7c10fd3515 Fix hypotf overflow/underflow by using double precision instead of scaling.
[BZ #13840]
	* sysdeps/ieee754/flt-32/e_hypotf.c (__ieee754_hypotf): Rewrite to use
	double-precision for the calculation instead of scaling.

0ac5ae2335 Optimize libm
libm is now somewhat integrated with gcc's -ffinite-math-only option
and lots of the wrapper functions have been optimized.
