tree-ssa-live.c (remove_unused_locals): Mark all edge's goto_block as used.

	* tree-ssa-live.c (remove_unused_locals): Mark all edge's goto_block
	as used.
	* gimple-low.c (lower_function_body, lower_gimple_return,
	lower_builtin_setjmp): Set gimple_block on the newly created stmts.
	* tree-cfg.c (make_cond_expr_edges, make_goto_expr_edges): Only set
	goto_block on edges if goto_locus is known.
