StatementTransformerThis transform may only modify instructions after and including the provided position. The transform will run from over the block backwards.
Instructions prior to the current position must not be modified. It is valid to read such instructions, but not recommended as those have not been transformed yet.
This function is only called on control-flow blocks with unreachable end-points.
This, the last instruction in the block must always have the InstructionFlag.END_POINT_UNREACHABLE flag.
