# When eliminating the unnecessary try and its catch block we turn the
# TryBoundary instructions into Goto instructions. If one of these
# instructions is pointing to the exit block, we use its single
# predecessor instead. If this TryBoundary-turned-into-Goto instruction
# was the only one pointing to the Exit, we also have to update the dominators.
