[Ada] Avoid spurious errors on dimensionality checking in GNATprove

[Ada] Avoid spurious errors on dimensionality checking in GNATprove

In the special GNATprove mode of the frontend, automatic inlining is
performed, which may lead to spurious errors on dimensionality checking.
Avoid performing this checking on inlined code, which has already been
checked for dimensionality errors.

There is no impact on compilation.

	checking on inlined bodies.
