* debug.adb: Remove d.A flag to delay address clause (not needed any
more). Add d.A flag to enable tree read/write of aspect spec hash table
* sem_ch13.adb (Analyze_Aspect_Specifications): Properly delay address
clause.
(Rep_Item_Too_Late): No need for special processing for delayed rep
items (and it caused difficulties in the address case).
* tree_gen.adb: Only write aspect spec hash table if -gnatd.A is set
* tree_in.adb: Only write aspect spec hash table if -gnatd.A is set
