New Revision: 154815

URL: http://llvm.org/viewvc/llvm-project?rev=154815&view=rev
Log:
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.
