Remove an overly brittle test. This test will no longer be interesting
once we start changing the block layout, so just nuke it. If anyone has ideas about how to craft a code layout agnostic form of the test please let me know. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@154815 91177308-0d34-0410-b5e6-96231b3b80d8
