Nick Lewycky 175e7aec13 Add the select optimization recently added to instcombine to constant folding. ... This is the one where one of the branches of the select is another select on the same condition. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@124547 91177308-0d34-0410-b5e6-96231b3b80d8		2011-01-29 20:35:06 +00:00
