            Bug ID: 33045
           Summary: AMDGPU check has a bunch of machine verifier errors
           Product: libraries
           Version: trunk
          Hardware: PC
                OS: Windows NT
            Status: NEW
          Severity: enhancement
          Priority: P
         Component: Backend: AMDGPU

Enabling machine code verification with EXPENSIVE_CHECKS
(https://reviews.llvm.org/D30625) causes a number of machine verifier errors
with `ninja check-codegen-amdgpu`:
