Subject: [Ada] Optimize code generated for array aggregate construction

This is a small optimization to avoid generating superfluous temporaries for
the construction of array aggregates.  If the bounds of the slice already are
of the base type of the index, there is no need to qualify them, which would
trigger the creation of various temporaries downhill.  No functional change.

Tested on x86_64-pc-linux-gnu, committed on trunk

	* exp_aggr.adb (Gen_Loop): Do not qualify the bounds of the range if
	they are already of the base type of the index.
