- Add encode bits for VEX_W
- All 128-bit SSE 1 & SSE2 instructions that are described
  in the .td file now have a AVX encoded form already working.

folding set map.  These entries used to be harmless, because
a SCEVUnknown doesn't store any information about its Value*,
so having a new Value allocated at the old Value's address
wasn't a problem. But now that ScalarEvolution is storing more
information about values, this is no longer safe.
