Generating more PGO-friendly debug information seems orthogonal to the others (but perhaps reasonable to default "on" when *using* a sample profile), so I would leave it as a separate flag entirely.

I don't have great naming ideas... I guess steal from the Clang name: `-new-pm-debug-info-for-profiling`.
