Collected instruction counts before and after this. A few extra instructions are generated due to spilling but it is normal to see these kinds of changes with almost any small codegen change, according to Jakob. This also fixed rdar://11830760 where xor is expected instead of movi0. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@160749 91177308-0d34-0410-b5e6-96231b3b80d8		2012-07-25 18:28:13 +00:00
