Keith Randall 611706b171 cmd/compile: don't use BTS when OR works, add direct memory BTS operations 
Stop using BTSconst and friends when ORLconst can be used instead.
OR can be issued by more function units than BTS can, so it could
lead to better IPC. OR might take a few more bytes to encode, but
not a lot more.

Still use BTSconst for cases where the constant otherwise wouldn't
fit and would require a separate movabs instruction to materialize
the constant. This happens when setting bits 31-63 of 64-bit targets.

Add BTS-to-memory operations so we don't need to load/bts/store.

Fixes #61694
