I should test that this crashes prior to my change, since the reproducer was found on ppc, though I don't think the issue is target specific. If so, I will pre-commit the additional test, and rebase this so we can better see the resulting changes to the test.

Cool; yeah, after I rebase I should add -verify-machineinstrs to this test; it now asserts for this addition with the assertion I added recently in D130290.
