H A Dtraps.cdiff fd3f1e0f139f1314ff97438eebaa1f9d216e10a2 Sun Feb 07 06:56:43 CST 2021 Nicholas Piggin <npiggin@gmail.com> powerpc/traps: factor common code from program check and emulation assist

Move the program check handling into a function called by both, rather
than have the emulation assist handler call the program check handler.

This allows each of these handlers to be implemented with "interrupt
wrappers" in a later change.
