Optimize concatenations that produce unused bits in DFG (#6971)
Concatenations that are only used by Sel expressions that do not consume
some bits on the edges can be narrowed to not compute the unused bits.

E.g.: `{a[4:0], b[4:0]}[5:4]` -> `{a[0], b[4]}[1:0]`

This is a superset or the PUSH_SEL_THROUGH_CONCAT DFG pattern, which is
removed.
