Chris Lattner ef0c6744d5 Teach jump threading to clean up after itself, DCE and constfolding the ... new instructions it simplifies. Because we're threading jumps on edges with constants coming in from PHI's, we inherently are exposing a lot more constants to the new block. Folding them and deleting dead conditions allows the cost model in jump threading to be more accurate as it iterates. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@60327 91177308-0d34-0410-b5e6-96231b3b80d8		2008-12-01 04:48:07 +00:00
