    [arm64] Update BuiltinContinuation frames for jssp alignment. · a63f045c
    Georgia Kouveli authored
    Adds some necessary padding to ensure the frame is 16-byte aligned.
    We don't yet consider the bailout state, which will be handled separately.
    
    This patch also improves the code generated for ContinueTo*Builtin* stubs.
    
    Finally, it adds a test that checks the return value for Array.map in
    the case where a LAZY deopt results in a topmost builtin continuation
    frame - this is easy to break if the padding for the result is done
    incorrectly in NotifyBuiltinContinuation, but was not detected by existing
    tests.
