<pre>In r200577 some FMA3 "sort-of"-insts (they're not pseudo-insts in the normal
sense, they're actual duplicate instructions with 'isCodeGenOnly' tags) were
replaced with def-pats. It may be possible to replace several similar
"sort-of"-insts in X86InstrSSE with similar pats. This would be a useful tidy
up and may (as r200577 did) expose some extra memory-folding opportunities.</pre>
