Alan Modra fa72205cb9 Allow self-assignment for absolute symbols defined in a linker script 
Modifies ld machinery tracking linker script assignments to notice all
assignments, not just those symbols mentioned in DEFINED().

ld/
	PR ld/14962
	* ldlang.h (struct lang_definedness_hash_entry): Add by_object and
	by_script.  Make iteration a single bit field.
	(lang_track_definedness, lang_symbol_definition_iteration): Delete.
	(lang_symbol_defined): Declare.
	* ldlang.c (lang_statement_iteration): Expand comment a little.
	(lang_init <lang_definedness_table>): Make it bigger.
	(lang_track_definedness, lang_symbol_definition): Delete.
	(lang_definedness_newfunc): Update.
	(lang_symbol_defined): New function.
	(lang_update_definedness): Create entries here.  Do track whether
	script definition of symbol is valid, even when also defined in
	an object file.
	* ldexp.c (fold_name <DEFINED>): Update.
	(fold_name <NAME>): Allow self-assignment for absolute symbols
	defined in a linker script.

	* ld-scripts/pr14962-2.d,
