Justin Hibbits a6ca7519f8 powerpc64: Optimize radix trap handling a little more 
Summary:
Since PCPU can live in a GPR for a while longer, let it, rather than
re-getting it in yet another register.  MFSPR is an expensive operation,
12 clock latency on POWER9, so the fewer operations we need, the better.

Since the check is tightly coupled to the fetch, by reducing the number
of fetch+check, we reduce the stalls, and improve the performance
marginally.  Buildworld was measured at a ~5-7% improvement on a single
run.
