The first commit is identical to
69bec0afbb8f2aa0021d18ea38768360b16583a9.
The second commit fixes the instruction verification failures by
replacing the erroneous instruction with a trap after the error is
reported and adds `-verify-machineinstrs` to the tests added in the
original PR to catch the issue sooner.
After that change, all tests pass with both
`LLVM_ENABLE_EXPENSIVE_CHECKS={On,Off}`.
