The generated code has been improved so that aggregates with <> are more
efficient. No change in behavior; no test.

* exp_aggr.adb (Expand_Array_Aggregate): Use build-in-place in
the nonlimited case in STEP 4. This improves the efficiency of
things like (1 .. 1000 => <>). We still generate some code for
that, unfortunately, but it is much improved.
(Aggr_Assignment_OK_For_Backend): Return false if <> components
are present.
