    Original Commit Message:
    
        Stack overflow checks are typically implemented as part of the TurboFan
        graph of a function. This means that the stack check code is executed
        after frame construction. When a frame is too big, though, there may not
        be enough space on the stack anymore to throw the stack overflow
        exception after frame construction. With this CL we do an additional
        stack check before frame construction for functions with big frames.
    
        As discussed offline with mstarzinger, I do this change currently only
        for WebAssembly.
    
        This CL contains only the changes for arm. I will do the other platforms
        in separate CLs
