rx.c (rx_option_optimization): Change to rx_override_options_after_change.

Browse Source 
* config/rx/rx.c (rx_option_optimization): Change to
	rx_override_options_after_change.  Don't change
	flag_lto_compression_level.  Don't check for changes to whether
	FPU instructions can be used.  Check and set only
	flag_finite_math_only, not other fast-math flags.
	(rx_option_override): Call rx_override_options_after_change.
	(TARGET_OPTION_OPTIMIZATION): Remove.
	(TARGET_OVERRIDE_OPTIONS_AFTER_CHANGE): Define.
