[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.

[MachineSink] Fix for breaking phi edges with instructions with multiple defs

BreakPHIEdge would be set based on whether the instruction needs to
insert a new critical edge to allow sinking into a block where the uses
are PHI nodes. But for instructions with multiple defs it would be reset
on the second def, allowing the instruciton to sink where it should not.
