	* opt.ads New global boolean Frame_Condition_Mode to avoid
	referring to command line switch.
	* gnat1drv.adb (Gnat1drv) set frame condition mode when -gnatd.G
	is present, and disable Code generation in that case. Disable
	ALI file generation when switch is *not* present.

	* sem_ch6.adb (Analyze_Expression_Function): Perform the
