* par-ch4.adb (P_Simple_Expression): Fold long sequences of
concatenations of string literals into a single literal, in order to
avoid very deep recursion in the front end, which was causing stack
overflow.
* sem_eval.adb (Eval_Concatenation): If the left operand is the empty
string, and the right operand is a string literal (the case of "" &
"..."), optimize by avoiding copying the right operand -- just use the
value of the right operand directly.
* stringt.adb (Store_String_Chars): Optimize by growing the
String_Chars table all at once, rather than appending characters one by
one.
(Write_String_Table_Entry): If the string to be printed is very long,
just print the first few characters, followed by the length. Otherwise,
doing "pn(n)" in the debugger can take an extremely long time.
* sem_prag.adb (Process_Interface_Name): Replace loop doing
Store_String_Char with Store_String_Chars.

* restrict.adb, namet.adb, par-util.adb: Remove redundant type

* sem_res.adb (Resolve_Qualified_Expression): Add machinery to detect

* exp_ch8.adb (Expand_N_Package_Renaming_Declaration): In the case of a
library-level package renaming, pass the declaration associated with
the renaming's special debug variable to Qualify_Entity_Names to ensure
that its encoded name is properly qualified.
* exp_dbug.adb (Qualify_All_Entity_Names): Check for a variable entity
occurring in the list of entities to qualify, and do not attempt to
traverse an entity list in that case. Variables associated with
` library-level package renamings can now occur in the table.
* exp_dbug.ads: Revise documentation of the encoding for renaming
declarations.
