Allow plugin dumps

Defer dump option parsing until plugins are initialized.  This allows one to
use plugin names for dumps.

	PR other/99451
	gcc/
	* opts.h (handle_deferred_dump_options): Declare.
	* opts-global.cc (handle_common_deferred_options): Do not handle
	dump options here.
	(handle_deferred_dump_options): New.
	* toplev.cc (toplev::main): Call it after plugin init.
