	* tree-inline.c (tree_function_versioning): Call cgraph_get_node
	instead of cgraph_node and assert it does not return NULL.
	* lto-streamer-in.c (lto_read_body): Likewise.
	* omp-low.c (new_omp_context): Likewise.
	(create_task_copyfn): Likewise.
	* tree-emutls.c (lower_emutls_function_body): Likewise.
	* matrix-reorg.c (transform_allocation_sites): Likewise.
