	* sem_ch10.adb (Analyze_Compilation_Unit): if a unit in the context is
	a generic subprogram that is imported, do not attempt to compile
	non-existent body.

	* sem_ch12.adb (Instantiate_Subprogram_Body): if the generic is
	imported, do not generate a raise_program_error for the non-existent
	body.
	(Pre_Analyze_Actuals): If an error is detected during pre-analysis,
	perform minimal name resolution on the generic to avoid spurious
	warnings.
	(Find_Actual_Type): the designated type of the actual in a child unit
	may be declared in a parent unit without being an actual.
