5245 return value from the negation of that parameter for Thumb-1, keeping
5246 the logic unchanged otherwise except for using bdst as the destination
5247 register of the compare_and_swap insn.

5249 returned to the function comment. Rename scratch variable to
5250 neg_bval. Adapt initialization of variables holding operands to the
5251 new operand numbers. Use return register to hold result of store
5252 exclusive for Thumb-1, scratch register otherwise. Construct the
5253 appropriate cbranch for Thumb-1 targets, keeping the logic unchanged
5254 for 32-bit targets. Guard Z flag setting to restrict to 32bit targets.
