*	Convert CodeGen//.ll tests to use the new CHECK-LABEL for easier ↵	Stephen Lin	2013-07-13
\| \| \| \| \| \| \| \| \| \| \|	debugging. No functionality change and all tests pass after conversion. This was done with the following sed invocation to catch label lines demarking function boundaries: sed -i '' "s/^;$ $$[A-Z0-9_]$:$ $test$[A-Za-z0-9_-]$:$ $$/;\1\2-LABEL:\3test\4:\5/g" test/CodeGen//*.ll which was written conservatively to avoid false positives rather than false negatives. I scanned through all the changes and everything looks correct. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@186258 91177308-0d34-0410-b5e6-96231b3b80d8
