Art: "Out of Registers" workaround.
The weekend is almost over, and the proper fix for b/15024623
isn't quite ready (CL 468162). Time for plan B.
This workaround CL avoids the bug by disabling local liveness
tracking and the associated reduntant load suppression.
Once CL 468162 is ready, they will be re-enabled.
