  [flang][hlfir] fix issue 118922 (#119219)

hlfir.elemental codegen optimize-out the final as_expr copy for temps
local to its body, but sometimes, clean-up may have been emitted for
this temp, and the code did not handle that.
This caused #118922 and @113843.

Only elide the copy if the as_expr is the last op.
