        Seems to only manifest on x86_32, and only with SSE=0. The test sets UseAVX=1, maybe that's the problem.

        $ CONF=linux-x86-server-fastdebug make run-test TEST=compiler/loopopts/superword/CoLocatePack.java TEST_VM_OPTS="-XX:UseAVX=0 -XX:UseSSE=0"
        ...

        CompileCommand: compileonly compiler/loopopts/superword/CoLocatePack.test bool compileonly = true
