Okay, but:

  - You should have mentioned that test in your commit message :).
  - You still need a test in LLVM that the right IR gets generated.
    Compiler-RT is an okay place for full-flow tests for PGO -- does
    it all work? -- but we should have a local test that this pass
    is generating the right IR.  I think the right place is
    test/Instrumentation/InstrProfiling/.

Not exactly sure what's wrong, but IME when this doesn't fix it:

$ git pull --rebase && git svn rebase -l

... this usually does:

$ rm -rf .git/svn
$ git svn rebase -l
