  Log Message:
  [AArch64][SVE] Add some logical operation DestructiveBinaryComm patterns

Add DestructiveBinaryComm* patterns for ORR, EOR, AND and BIC.
The above instructions requires that the source and destination registers are
equal, so use movprfx should be beneficial to performance.
note: BIC (i.e. A & ~B) is not a commutative operation.
