* powerpc.cc (class Powerpc_relobj): Move some member functions.

	(Target_powerpc::symval_for_branch):  Add symtab param.  Update
	all callers.  Handle folded sections.
	(Target_powerpc::do_gc_add_reference): Don't cast dynamic object
	to Powerpc_relobj.
	(Global_symbol_visitor_opd::operator()): Likewise.
