cstand.adb (Create_Standard): Change Import_Code component of Standard_Exception_Type to Foreign_Data.

2013-10-14  Tristan Gingold  <gingold@adacore.com>

	* cstand.adb (Create_Standard): Change Import_Code component
	of Standard_Exception_Type to Foreign_Data. Its type is now
	Standard_A_Char (access to character).
	* exp_prag.adb (Expand_Pragma_Import_Export_Exception): Adjust
	definition of Code to match the type of Foreign_Data.
	* s-stalib.ads (Exception_Data): Replace Import_Code by Foreign_Data
	Change the definition of standard predefined exceptions.
	(Exception_Code): Remove.
	* raise.h (Exception_Code): Remove (Exception_Data): Replace
	Import_Code field by Foreign_Data.
	* rtsfind.ads (RE_Exception_Code): Remove
	(RE_Import_Address): Add.
	* a-exexpr-gcc.adb (Import_Code_For): Replaced by Foreign_Data_For.
	* exp_ch11.adb (Expand_N_Exception_Declaration): Associate null
	to Foreign_Data component.
	* raise-gcc.c (Import_Code_For): Replaced by Foreign_Data_For.
	(is_handled_by): Add comments. Use replaced function. Change
	condition so that an Ada occurrence is never handled by
	Foreign_Exception.
	* s-exctab.adb (Internal_Exception): Associate Null_Address to
	Foreign_Data component.
	* s-vmexta.adb, s-vmexta.ads (Exception_Code): Declare Replace
	SSL.Exception_Code by Exception_Code.
