There is one failure in the pre-submit tests which I believe is unrelated to this change:
`compiler/vectorization/runner/LoopRangeStrideTest.java`

TEST RESULT: Failed. Execution failed: `main' threw exception: compiler.lib.ir_framework.driver.irmatching.IRViolationException: There were one or multiple IR rule failures. Please check stderr for more information.
