Fix spurious auto-formats and typo

The typo in GCNSubtarget::getMaxNumArchVGPRs made the function return
the wrong value in all cases. The returned value is now correct; this
causes some unit tests to break in largely cosmetic ways, since that
value is used to calculate excess RP in the remat stage.
