I think you should probably move this into a separate MIR test:
* The RUN line is generating MIR and the other tests are generating ASM
* The existing tests are using update_llc_test_checks and you are writing manual checks
* update_llc_test_checks is the wrong script to use if you were auto-generating tests for this RUN line
* The IR is small
