New Revision: 77986

URL: http://llvm.org/viewvc/llvm-project?rev=77986&view=rev
Log:
Make SimplifyDemandedUseBits generate vector constants where 
appropriate.  Patch per report on llvmdev.  No testcase because the 
original report didn't come with a testcase, and I can't come up with a case
that actually fails.
