    [turbofan] Move large array allocation bailout earlier · 930f2654
    Maya Lekova authored
    The CanAllocateArray used to be executed during JSCreateLowering,
    leading to bailouts when large arrays are passed as arguments to
    an async function or a bound function. This meant that
    JSCreateAsyncFunctionObject or JSCreateBoundFunction will reach
    JSGenericLowering, where they are not lowered. This CL moves
    the checks earlier in the pipeline during JSNativeContextSpecialization
    and JSCallReducer respectively, so that those operators are not
    created at all in such cases and we bail out to the runtime instead.
