[ARM] Make MachineVerifier more strict about terminators

Fix the ARM backend's analyzeBranch so it doesn't ignore predicated
return instructions, and make the MachineVerifier rule more strict.

[DAGCombiner] Rebuild (setcc x, y, ==) from (xor (xor x, y), 1)

The existing code already considered this case. Unfortunately a typo in
the condition prevents it from triggering. Also the existing code, had
it run, forgot to do the folding.

This fixes PR42876.

[NFC] Add tests for boolean comparisons

They currently show that the not equal case may be improved.
