68b047d094 [turbofan] Fix lowering of JSGetSuperConstructor. 
This fixes the existing lowering of {JSGetSuperConstructor} nodes to
unconditional throws. The above operator is marked as {kNoWrite} but
runtime calls are not marked as such. Any deoptimizing operation after
the throw would not be able to find a valid {Checkpoint}. We remove the
lowering case in question.
