Patch to Bug 94022 - Array slices of assumed-size arrays.

Patch to Bug 94022 - Array slices of assumed-size arrays.

Make sure that when passing array sections of assumed-size arrays to
procedures expecting an assumed-rank array the upper bound of the
last dimension of the array section does not get improperly reset
to -1 to mark it has an assumed size array.
