sse.md (*sse2_maskmovdqu): Emit addr32 prefix when Pmode != word_mode.

Browse Source 
* config/i386/sse.md (*sse2_maskmovdqu): Emit addr32 prefix
	when Pmode != word_mode.  Add length_address attribute.
	(sse3_monitor_<mode>): Merge from sse3_monitor and
	sse3_monitor64_<mode> insn patterns.  Emit addr32 prefix when
	Pmode != word_mode.  Update insn length attribute.
	* config/i386/i386.c (ix86_option_override_internal): Update
	ix86_gen_monitor selection for merged sse3_monitor insn.
