Chris Lattner a09fbf0af0 switch GVN to use SSAUpdater. Besides removing a lot of complexity ... from GVN, this also speeds it up, inserts fewer PHI nodes (see the testcase) and allows it to remove more loads (due to fewer PHI nodes standing in the way). git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@83746 91177308-0d34-0410-b5e6-96231b3b80d8		2009-10-10 23:50:30 +00:00
