@jhuber6 The clang format errors are mostly due to my local version of `clang-format` disagreeing with the buildbot's version. Its a bit annoying, but it shouldn't be too much of a problem given I plan on squashing and merging once this gets approved.

I added new flags for GPU PGO specifically because I didn't want to modify the PGO flags' existing behavior. PGO has a significant runtime cost, so I figured it would be best for the end user experience to only enable PGO on the GPU when it was specifically requested.
