* Keep Touch'd variables live through the back end
Ignore-this: 2abe470d7c80b38441e1c25b3d081c6f
When we used derived pointers into the middle of an object,
we need to keep the pointer to the start of the object live.
We use a "fat machine instruction" with the primitive MO_Touch
to propagate this information through the back end.
