  [DAG] Add TODO to remove creation of INSERT_SUBVECTOR nodes from SimplifyMultipleUseDemandedBits

SimplifyMultipleUseDemandedBits shouldn't be creating general nodes like this - although we allow bitcasts, even general constant folding is avoided.

Removing it causes a number of regressions that need addressing first, but I've added a TODO for now.
