  Log Message:
  -----------
  [flang][hlfir] Evaluate actual args before impure elemental calls.

Actual argument expressions must be evaluated before the invocation
of the sequence of per-element calls of an impure elemental subprogram.
Otherwise, the side effects of the calls may affect the input for
the consequent elements.
The proposed changes are described by Jean in D154174.
