Update these tests to not use the same name even though the type of the value differs. After PR411 hits, type planes will be gone and it will be illegal for a name to be used twice, regardless of type. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@33660 91177308-0d34-0410-b5e6-96231b3b80d8
