Lynn Boger eeca3ba92f sync/atomic, runtime/internal/atomic: improve ppc64x atomics 
The following performance improvements have been made to the
low-level atomic functions for ppc64le & ppc64:

- For those cases containing a lwarx and stwcx (or other sizes):
sync, lwarx, maybe something, stwcx, loop to sync, sync, isync
The sync is moved before (outside) the lwarx/stwcx loop, and the
 sync after is removed, so it becomes:
sync, lwarx, maybe something, stwcx, loop to lwarx, isync

- For the Or8 and And8, the shifting and manipulation of the
address to the word aligned version were removed and the
instructions were changed to use lbarx, stbcx instead of
register shifting, xor, then lwarx, stwcx.

- New instructions LWSYNC, LBAR, STBCC were tested and added.
runtime/atomic_ppc64x.s was changed to use the LWSYNC opcode
instead of the WORD encoding.

Fixes #15469

Ran some of the benchmarks in the runtime and sync directories.
Some results varied from run to run but the trend was improvement
based on best times for base and new:
