* sem.ads (Scope_Stack_Entry): Reorganize storage of action lists;
introduce a new list (cleanup actions) for each (transient) scope.
* sinfo.ads, sinfo.adb (Cleanup_Actions): New attribute for
N_Block_Statement
* exp_ch7.ads (Store_Cleanup_Actions_In_Scope): New subprogram.
* exp_ch7.adb (Store_Actions_In_Scope): New subprogram, common
processing for Store_xxx_Actions_In_Scope.
(Build_Cleanup_Statements): Allow for a list of additional
cleanup statements to be passed by the caller.
(Expand_Cleanup_Actions): Take custom cleanup actions associated
with an N_Block_Statement into account.
(Insert_Actions_In_Scope_Around): Account for Scope_Stack_Entry
reorganization (refactoring only, no behaviour change).
(Make_Transient_Block): Add assertion to ensure that the current
scope is indeed a block (namely, the entity for the transient
block being constructed syntactically, which has already been
established as a scope). If cleanup actions are present in the
transient scope, transfer them now to the transient block.
* exp_ch6.adb (Expand_Protected_Subprogram_Call): Freeze the
called function while it is still present as the name in a call
in the tree. This may not be the case later on if the call is
rewritten into a transient block.
* exp_smem.adb (Add_Shared_Var_Lock_Procs): The post-actions
inserted after calling a protected operation on a shared passive
protected must be performed in a block finalizer, not just
inserted in the tree, so that they are executed even in case of
a normal (RETURN) or abnormal (exception) transfer of control
outside of the current scope.
* exp_smem.ads (Add_Shared_Var_Lock_Procs): Update documentation
* sem_ch8.adb, expander.adb, exp_ch11.adb: Adjust for
Scope_Stack_Entry reorganization.

* exp_disp.adb (Make_DT, Make_VM_TSD): Do not omit Check_TSD
call for types that do not have an explicit attribute definition
clause for External_Tag, as their default tag may clash with an
explicit tag defined for some other type.

* exp_util.adb (Is_Controlled_Function_Call): Recognize a
controlled function call with multiple actual parameters that
appears in Object.Operation form.
2014-07-17 Thomas Quinot <quinot@adacore.com>
* einfo.ads, einfo.adb (Has_External_Tag_Rep_Clause): Remove
entity flag.
* sem_ch13.adb (Analyze_Attribute_Definition_Clause, case
External_Tag): No need to set entity flag.
* sem_aux.ads, sem_aux.adb (Has_External_Tag_Rep_Clause):
Reimplement correctly in terms of Has_Rep_Item.
