Optimizing: ARM64 negated bitwise operations simplification
Use negated instructions on ARM64 to replace [bitwise operation + not]
patterns, that is:
a & ~b (BIC)
a | ~b (ORN)
a ^ ~b (EON)
The simplification only happens if the Not is only used by the bitwise
operation. It does not happen if both inputs are Not's (this should be
handled by a generic simplification applying De Morgan's laws).
