Emit CheckFoo instead of GuardFoo if the region entry block is a loop header.
Summary: Also rename a lot of stuff named "unprocessedPred" as "loopHeader".
This can generate suboptimal translations as we'll have loopy PGO
translations with no retranslate exits. The plan going forward is to
have an post-processing pass to fix these translations up, but for now,
let's just get this correct.
