Port 10c5f2e8

Original commit message:
    Slow path for relational comparison of boolean primitive values
    now goes through the runtime, which made the slow path even
    slower than it already was. So in order to repair the regression,
    we just track boolean feedback for comparisons and use that
    to generate decent code in Crankshaft (not the best possible
    code, but good enough for Crankshaft; TurboFan will be able
    to do better on that).
