In opt, the option is named '-auto-profile' when I instantiate the pass:

INITIALIZE_PASS(AutoProfile, "auto-profile", "Auto Profile loader", false,
                false)

Do I need to name it fauto-profile as well?

I'm also not sure how to schedule the pass at a specific spot in the
pass manager.  I've looked around for documentation on adding flags,
but all I found was
http://llvm.org/docs/WritingAnLLVMPass.html#pass-registration which
does not seem to discuss this.
