6614 return value from the negation of that parameter for Thumb-1, keeping
6615 the logic unchanged otherwise except for using bdst as the destination
6616 register of the compare_and_swap insn.

6618 returned to the function comment. Rename scratch variable to
6619 neg_bval. Adapt initialization of variables holding operands to the
6620 new operand numbers. Use return register to hold result of store
6621 exclusive for Thumb-1, scratch register otherwise. Construct the
6622 appropriate cbranch for Thumb-1 targets, keeping the logic unchanged
6623 for 32-bit targets. Guard Z flag setting to restrict to 32bit targets.
