This changes the type set on bit references made to packed arrays:
instead of Universal_Integer, it is set to Standard.Natural.
The reason is that Universal_Integer must be a type as large as the
largest supported integer type and, therefore, can be much larger than
what is really needed here.
No functional changes.
Tested on x86_64-pc-linux-gnu, committed on trunk
