i386.c (override_options): Set defaults for flag_omit_frame_pointer...

Browse Source 
* i386.c (override_options): Set defaults for flag_omit_frame_pointer,
	flag_asynchronous_unwind_tables, flag_pcc_struct_return.
	* i386.c (optimization_options): Set flag_omit_frame_pointer,
	flag_asynchronous_unwind_tables, flag_pcc_struct_return to 2.
	Do not clear -momit-leaf-frame-pointer when profiling.
	(ix86_frame_pointer_required): Frame pointer is allways required when
	profiling.
