	* config/i386/i386.c (ix86_option_override_internal): Properly
	set ix86_gen_leave and ix86_gen_monitor.  Check Pmode == DImode,
	instead of TARGET_64BIT, to set ix86_gen_add3, ix86_gen_sub3,
	ix86_gen_one_cmpl2, ix86_gen_andsp,
	ix86_gen_allocate_stack_worker, ix86_gen_adjust_stack_and_probe
	and ix86_gen_probe_stack_range.

	* config/i386/sse.md (sse3_monitor64): Renamed to ...
	(sse3_monitor64_<mode>): This.
