455e169d7cad4499ed9f4647215b9ec71aa706e4 Hexagon (target/hexagon) Short-circuit packet predicate writes
In certain cases, we can avoid the overhead of writing to hex_new_pred_value
and write directly to hex_pred. We consider predicate reads/writes when
computing ctx->need_commit. The get_result_pred() function uses this
field to decide between hex_new_pred_value and hex_pred. Then, we can
early-exit from gen_pred_writes.
