[Ada] Refine conditions for calling Copy_Bitfield

Avoid calling Copy_Bitfield if there are volatile or independent
components that might be read or written. The test is conservative.

* exp_ch5.adb (Expand_Assign_Array_Loop_Or_Bitfield): Add tests
for potential volatile or independent components.
* libgnat/s-bituti.adb (Copy_Small_Bitfield,
Copy_Large_Bitfield): Move declarations to more appropriate
place.
