ada: Use context variables in expansion of aggregates

Code cleanup; semantics is unaffected.

gcc/ada/

	* exp_aggr.adb
	(Build_Constrained_Type): Remove local constants that were shadowing
	equivalent global constants; replace a wrapper that calls
	Make_Integer_Literal with a numeric literal; remove explicit
	Aliased_Present parameter which is equivalent to the default value.
	(Check_Bounds): Remove unused initial value.
	(Expand_Array_Aggregate): Use aggregate type from the context.
