    original commit message:
    
        Array() in optimized code can create with wrong ElementsKind in corner cases.
    
        Calling new Array(JSObject::kInitialMaxFastElementArray) in optimized code
        makes a stub call that bails out due to the length. Currently, the bailout
        code a) doesn't have the allocation site, and b) wouldn't use it if it did
        because the length is perceived to be too high.
    
        This CL passes the allocation site to the stub call (rather than undefined),
        and alters the bailout code to utilize the feedback.
