cobol: Improved handling of COBOL Special Registers.

COBOL Special Registers (e.g., RETURN-CODE; DEBUG-ITEM) are implemented as
global variables.  These changes define them with the prefix "__ggsr__" in
their variable names so that the GDB-COBOL debugger can identify them.

The creation and handling of such variables has been streamlined with the
introduction of the "register_e" cbl_field_t::attr bit.

gcc/cobol/ChangeLog:

	* genapi.cc (trace1_init): Prepend two internal variables with
	underscore.
	(initialize_variable_internal): Use new register_e attribute.
	(psa_global): Use "__ggsr__" prefix to identify special registers
	(parser_symbol_add): Use new register_e attribute.
	* symbols.cc (cbl_field_attr_str): Likewise.
	(symbol_table_init): Likewise.
	(is_register_field): Eliminated in favor of (attr & register_e).
	* symbols.h (is_register_field): Likewise.

libgcobol/ChangeLog:

	* common-defs.h (enum cbl_field_attr_t): Define register_e.
	* constants.cc (struct cblc_field_t): Define special registers with
	"__ggsr__" prefix.
