[PATCH] Add missing breaks to AArch64InstrInfo::is{G,F}PRCopy

[Tim Northover]

Hi Renato,

I think this one's reasonable. The lack of tests it a bit disturbing, but fine in my opinion (constructing one would be very difficult, with a very fragile result). The change is obviously correct.

Cheers.

Tim.
