[Ada] Fix internal error on packed array In/Out actual parameter
This fixes an issue introduced in Ada 2012 for calls to functions taking
an In/Out parameter and for which the actual is the component of a
packed array. In this case, the front-end needs to create a temporary
for the actual, initialize it before the call and assign it back after
it, because operations on bit-packed arrays are converted into
mask-and-shift sequences.
