    [wasm] Distinguish requested tier and executed tier · 185922de
    Clemens Hammacher authored
    During execution, the tier can be switch from Liftoff to TurboFan. We
    already handle this in some locations by getting the tier before
    execution, so that we later know which was the requested tier for that
    unit.
    In the case of the --wasm-tier-mask-for-testing flag, this accounting
    was not right because the tier was already switched in the constructor.
    This CL changes the compilation units to store both the requested and
    the executed tier explicitly, so we know which counter to decrement
    when the unit finishes.
