  [AggressiveInstCombine] Support store merge with non-consecutive parts (#149807)

This is a minor extension of #147540, resolving one of the FIXMEs. If
the collected parts contain some non-consecutive elements, we can still
handle smaller ranges that *are* consecutive.

This is not common in practice and mostly shows up when the same value
is stored at two different offsets.
