Nick Lewycky 4333f49afe Reinstate this optimization to fold icmp of xor when possible. Don't try to ... turn icmp eq a+x, b+x into icmp eq a, b if a+x or b+x has other uses. This may have been increasing register pressure leading to the bzip2 slowdown. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@63487 91177308-0d34-0410-b5e6-96231b3b80d8		2009-01-31 21:30:05 +00:00
