The toxic stew of created values named 'tmp' and tests that already have values named 'tmp' and CHECK lines looking for values named 'tmp' causes bad things to happen in our test line auto-generation scripts because it wants to use 'TMP' as a prefix for unnamed values. Use less 'tmp' to avoid that. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@317818 91177308-0d34-0410-b5e6-96231b3b80d8
