  -----------
  [flang] Improve designate/elemental indices match in opt-bufferization. (#121371)

This pattern appears in `tonto`: `rys1%w = rys1%w * ...`, where
component `w` is a pointer. Due to the computations transforming
the elemental's one-based indices to the array indices,
the indices match check did not pass in opt-bufferization.
This patch recognizes this indices adjusting pattern,
and returns the one-based indices for the designator.
