* debug.adb: Add -gnatdM for modified ALI output

* lib-xref.adb: Extend generation of <..> notation to cover
subtype/object types. Note that this is a complete rewrite,
getting rid of the very nasty quadratic algorithm previously
used for derived type output.
* lib-xref.ads: Extend description of <..> notation to cover
subtype/object types. Uses {..} for these other cases.
Also use (..) for pointer types.
* sem_util.adb (Check_Potentially_Blocking_Operation): Slight cleanup.
* exp_pakd.adb: Minor reformatting. Note that prevous RH should say:
(Known_Aligned_Enough): Replaces Must_Be_Aligned.
