re PR c++/26917 (ICE with -frepo on invalid code)

	PR c++/26917
	* repo.c (repo_file): Remove.
	(open_repo_file, reopen_repo_file_for_write): Return fopened
	FILE * instead of setting global repo_file variable.
	(init_repo): Adjust caller.
	(finish_repo): Likewise.  Return instead of goto out before
	reopen_repo_file_for_write has been called.
