Fix big-endian aggregate assignment in Ada
A bug internal to AdaCore notes that assigning a non-scalar value to
an element of a packed array will sometimes fail.
The bug turns out to be that ada_value_assign incorrectly computes the
starting point for the assignment. This patch fixes the problem.

for big-endian copies.
