New Revision: 157699

URL: http://llvm.org/viewvc/llvm-project?rev=157699&view=rev
Log:
it's pointed out that R11 can be used for magic things, and doing things just for 64-bit registers is silly.  Just optimize 3 more.

Added:
    llvm/trunk/test/CodeGen/X86/pass-three.ll
      - copied, changed from r157698, llvm/trunk/test/CodeGen/X86/pass-four.ll
Removed:
