Make set_fast_math_flags and set_unsafe_math_optimizations_flags static

After my RX options cleanup
<http://gcc.gnu.org/ml/gcc-patches/2010-10/msg01331.html> nothing
outside of opts.c uses set_fast_math_flags.  Also, nothing outside of
opts.c uses set_unsafe_math_optimizations_flags.  This patch makes
those functions static, removing their prototypes from toplev.h (which
isn't a good place to prototype functions in opts.c anyway; opts.h or
flags.h would be better).

Bootstrapped with no regressions on x86_64-unknown-linux-gnu.  OK to
commit?

	* opts.c (set_fast_math_flags,
	set_unsafe_math_optimizations_flags): Make static.
	* toplev.h (set_fast_math_flags,
	set_unsafe_math_optimizations_flags): Remove prototypes.
