Use the query that doesn't assert if TracksLiveness isn't set, which needs to always be available. We also need to start printing liveins regardless of TracksLiveness.
This directory contains tests for the MIR file format parser and printer. It was necessary to split the tests across different targets as no single target covers all features available in machine IR. Tests for codegen passes should NOT be here but in test/CodeGen/sometarget. As a rule of thumb this directory should only contain tests using 'llc -run-pass none'.
