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.
