Removal of ineffective use-clauses.
* exp_ch9.adb (Is_Simple_Barrier_Name): Check for false positives with
constant folded barriers.
* ghost.adb, sprint.adb, sem_ch10.adb, sem_warn.adb: Change access to
Subtype_Marks and Names list in use-clause nodes to their new singular
counterparts (e.g. Subtype_Mark, Name).
* par.adb, par-ch8.adb (Append_Use_Clause): Created to set
Prev_Ids and More_Ids in use-clause nodes.
(P_Use_Clause): Modify to take a list as a parameter.
(P_Use_Package_Clause, P_Use_Type_Clause): Divide names and
subtype_marks within an aggregate use-clauses into individual clauses.
* par-ch3.adb, par-ch10.adb, par-ch12.adb: Trivally modify call to
P_Use_Clause to match its new behavior.
* sem.adb (Analyze): Mark use clauses for non-overloaded entities.
* sem_ch4.adb (Try_One_Interp): Add sanity check to handle previous
errors.
* sem_ch6.adb (Analyze_Generic_Subprogram_Body,
Analyze_Subprogram_Body_Helper): Update use clause chain at the end of
the declarative region.
* sem_ch7.adb (Analyze_Package_Body_Helper): Update use clause chain
after analysis (Analyze_Package_Specification): Update use clause chain
when there is no body.
* sem_ch8.ads, sem_ch8.adb (Analyze_Use_Package, Analyze_Use_Type): Add
parameter to determine weither the installation of scopes should also
propagate on the use-clause "chain".
(Mark_Use_Clauses): Created to traverse use-clause chains and determine
what constitutes a valid "use" of a clause.
(Update_Use_Clause_Chain): Created to aggregate common machinary used
to clean up use-clause chains (and warn on ineffectiveness) at the end
of declaritive regions.
* sem_ch8.adb (Analyze_Package_Name): Created to perform analysis on a
package name from a use-package clause.
(Analyze_Package_Name_List): Created to perform analysis on a list of
package names (similar to Analyze_Package_Name).
(Find_Most_Prev): Created to traverse to the beginning of a given
use-clause chain.
(Most_Decendant_Use_Clause): Create to identify which clause from a
given set is highest in scope (not always the most prev).
(Use_One_Package, Use_One_Type): Major cleanup and reorganization to
handle the new chaining algorithm, also many changes related to
redundant clauses. A new parameter has also been added to force
installation to handle certain cases.
* sem_ch9.adb (Analyze_Entry_Body, Analyze_Protected_Body,
Analyze_Task_Body): Mark use clauses on relevant entities.
* sem_ch10.adb, sem_ch10.ads (Install_Context_Clauses,
Install_Parents): Add parameter to determine weither the installation
of scopes should also propagate on the use-clause "chain".
* sem_ch12.adb (Inline_Instance_Body): Add flag in call to
Install_Context to avoid redundant chaining of use-clauses.
* sem_ch13.adb: Minor reformatting.
* sem_res.adb (Resolve): Mark use clauses on operators.
(Resolve_Call, Resolve_Entity_Name): Mark use clauses on relevant
entities.
* sinfo.adb, sinfo.ads (Is_Effective_Use_Clause,
Set_Is_Effective_Use_Clause): Add new flag to N_Use_Clause nodes to
represent any given clause's usage/reference/necessity.
(Prev_Use_Clause, Set_Prev_Use_Clause): Add new field to N_Use_Clause
nodes to allow loose chaining of redundant clauses.
(Set_Used_Operations, Set_Subtype_Mark, Set_Prev_Ids, Set_Names,
Set_More_Ids, Set_Name): Modify set procedure calls to reflect
reorganization in node fields.
* types.ads (Source_File_Index): Adjust index bounds.
(No_Access_To_Source_File): New constant.

* sem_ch13.adb (Analyze_One_Aspect): In ASIS mode make a full copy of
the expression to be used in the generated attribute specification
(rather than relocating it) to avoid resolving a potentially malformed
tree when the expression is resolved through an ASIS-specific call to
Resolve_Aspect_Expressions. This manifests itself as a crash on a
function with parameter associations.
