Keith Randall 6aa1e6d52d [release-branch.go1.18] cmd/compile: fix conditional move rule on PPC64
Similar to CL 456556 but for ppc64 instead of arm64.

Change docs about how booleans are stored in registers for ppc64.
We now don't promise to keep the upper bits zeroed; they might be junk.

To test, I changed the boolean generation instructions (MOVBZload* and ISEL*
with boolean type) to OR in 0x100 to the result. all.bash still passed,
so I think nothing else is depending on the upper bits of booleans.

Update #57211
