cmd/compile/internal/ssa: optimize (AND (MOVDconst [-1] x)) on PPC64
This sequence can show up in the lowering pass on PPC64. If it
makes it to the latelower pass, it will cause an error because
it looks like it can be turned into RLDICL, but -1 isn't an
accepted mask.
Also, print more debug info if panic is called from
encodePPC64RotateMask.
Fixes #62698
