[Patch, fortran] PR47844 - Array stride ignored for pointer-valued function results

[Paul Richard Thomas]

Dear All,

As the testcase shows, pointer array functions can return strides that
are different to their initial values before the function call.  This
fix makes use of the descriptor strides since they are returned
durectly.

Bootstrapped and regtested of x86_64/FC9 - OK for trunk?

Cheers

Paul
