re PR middle-end/64067 (ICE in expand_expr_real_1, at expr.c:10540, involving compound literal shenanigans) 

PR middle-end/64067
	* expr.c (expand_expr_addr_expr_1) <case COMPOUND_LITERAL_EXPR>:
	Handle it by returning address of COMPOUND_LITERAL_EXPR_DECL
	not only if modifier is EXPAND_INITIALIZER, but whenever
	COMPOUND_LITERAL_EXPR_DECL is non-NULL and TREE_STATIC.

	* gcc.c-torture/compile/pr64067.c: New test.
