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

-; Prior to fixing PR10920 401.bzip miscompile, the coalescer would
-; consider vreg1 and vreg27 to be copies of the same value. It would
-; then remove one of the critical edge copes, which cannot safely be removed.
