re PR target/19116 (-funsafe-math-optimizations make nan compares equal to one another (-finite-math-only should be doing that))

2006-10-21  Richard Guenther  <rguenther@suse.de>

	PR target/19116
	* config/i386/i386.c (override_options): Do not set MASK_IEEE_FP
	if flag_unsafe_math_optimizations is specified.  We have
	flag_finite_math_only for that.
	* config/i386/i386.md (sqrtxf2): Do not require TARGET_IEEE_FP
	or flag_unsafe_math_optimizations.
