dwarf2out.c (dwarf2out_abstract_function): Do not change cfun.

2012-09-11  Martin Jambor  <mjambor@suse.cz>

	* dwarf2out.c (dwarf2out_abstract_function): Do not change cfun.
	(premark_used_types): New parameter fun, use it instead of cfun.
	(gen_subprogram_die): Use DECL_STRUCT_FUNCTION (decl) instead of cfun,
	also pass it to premark_used_types.
