Remove "target endian/pointersize" or add "target datalayout" to make the test parse properly or set the datalayout because defaults changes. For PR645: Make global names use the @ prefix. For llvm-upgrade changes: Fix test cases or completely remove use of llvm-upgrade for test cases that cannot survive the new renaming or upgrade capabilities. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@33533 91177308-0d34-0410-b5e6-96231b3b80d8
