* vms_data.ads: Minor reformatting
* einfo.ads, einfo.adb (Parent_Subtype): Now allowed on record subtype,
applies to base type.
(Parent_Subtype): Now allowed on record subtype, applies to base type
* exp_ch5.adb (Expand_Assign_Record): Handle Componentwise_Assignment
for case of fully repped tagged type.
(Make_Tag_Ctrl_Assignment): Set Componentwise_Assignment and avoid
tag save/restore for fully repped tagged type case.
* exp_util.ads, exp_util.adb (Is_Fully_Repped_Tagged_Type): New function
* fe.h (Is_Fully_Repped_Tagged_Type): New function
* sem_ch13.adb (Analyze_Recorrd_Representation_Clause): Check for
overlap of tagged type components with parent type if parent type is
fully repped.
* sinfo.ads, sinfo.adb (Componentwise_Assignment): New flag
* sem_res.adb (Check_No_Direct_Boolean_Operators): Remove handling of
comparisons.
(Resolve_Comparison_Operators): Remove No_Direct_Boolean_Operators check
(Resolve_Equality_Op): Remove No_Direct_Boolean_Operators check
* gnat_rm.texi: Restriction No_Direct_Boolean_Operators includes only
logical operators (AND/OR/XOR), not comparison operators.
* sprint.ads: Minor reformatting

* sem_intr.adb (Check_Intrinsic_Call): For Import_Value and related
intrinsics, check that argument is a string literal, rather than
checking for staticness.
