Inputs are based on argument reductions from generic and powerpc
implementation.

Checked on powerpc-linux-gnu (built without --with-cpu, with
--with-cpu=power4 and with --with-cpu=power5+ and --disable-multi-arch),
powerpc64-linux-gnu (built without --with-cp and with --with-cpu=power5+
and --disable-multi-arch).

	* benchtests/Makefile (bench-math): Add hypot.
	* benchtests/hypot-inputs: New file.
