Profiling instrumentation seems orthogonal to PIC. Could you keep the calls to `addPS4ProfileRTArgs` in their original locations?

This tests whether ArgList::hasFlag() works. It doesn't really stress your patch. Please omit it.

Looks identical to line 9. Unless I'm missing something, this should be removed.
