[Ada] Use renamings in GNATprove mode for side-effects extraction
In the GNATprove mode for formal verification, prefer renamings over
declaration of a constant to extract side-effects from expressions,
whenever the constant could be of an owning type, as declaring a
constant of an owning type has an effect on ownership which is
undesirable.
There is no impact on compilation.

* exp_util.adb (Remove_Side_Effects): Prefer renamings for
objects of possible owning type in GNATprove mode.
