They are always used together, and can actually be simplified when combined. This transform cannot currently deal with shadowing, and will need need to depend on a new 'unshadow' transform. Fixes a long-standing bug where we'd get an ICE if we attempt to inline a pointer let declaration with side-effects in a for-loop initializer.
