>> When handling a scalarized return from an inlined method handle call in C2, we assert that we always make use of the buffer that we pre-allocated before the call. The assert is too strong because we could stop parsing in the callee due to an uncommon trap. I added a corresponding test that triggers this because we trap in the callee due to always throwing an exception.
