Log message:
	* gimplify.c (gimplify_*): Return gimplify_status.
	(gimple_add_tmp_var): Set seen_in_bind_expr.
	(gimplify_bind_expr): Likewise.  Kill if 0 code.
	(gimplify_return_expr): Cope with error marks.
	(gimple_push_cleanup): Do nothing if errors seen.
	(gimplify_expr): Cope with error marks.  Use gimplify_status to
	decide when to exit the main loop.  Zap statements with errors.
	(gimplify_body): Return void.
	(keep_function_tree_in_gimple_form): Don't exit on errors.
	(gimplify_function_tree): Return bool.  Don't exit on errors.
	* langhooks.c (lhd_gimplify_expr): Return GS_UNHANDLED.
	* langhooks.h (struct lang_hooks): Update docs for gimplify_expr.
	* tree-optimize.c (optimize_function_tree): Don't exit on errors.
	Move delete_tree_cfg call outside optimization clause.
	(tree_rest_of_compilation): Don't exit on errors.
	* tree-simple.h (enum gimplify_status): New.
	(gimplify_expr, gimplify_stmt, gimplify_body): Update.
	* tree-ssa.c (rewrite_out_of_ssa): Move delete_tree_cfg call to
	optimize_function_tree.
	* tree.h (struct tree_decl): Add seen_in_bind_expr.
	(gimplify_function_tree): Update.
	* c-common.c (c_add_case_label): Unify three error exit paths.
	Create a normal label, not a case label to suppress unreachable
	code warning.
	* c-simplify.c (c_build_bind_expr): Don't create an empty bind
	body.  Pass entire bind_expr to gimplify_stmt.
	(gimplify_block): Don't abort on mismatches if errors seen.
	(gimplify_expr_stmt): Cope with error marks.
	(gimplify_decl_stmt): Likewise.
	(c_gimplify_expr): Return gimplify_status.
	cp/
	* cp-simplify.c (cp_gimplify_expr): Return gimplify_status.
	fortran/
	* f95-lang.c (gfc_gimplify_expr): Return gimplify_status.
	java/
	* java-gimplify.c (java_gimplify_expr): Return gimplify_status.
