* tree-nested.c (walk_stmt_info): Add changed field.
(convert_nonlocal_reference): Set changed to when we
change a decl to unnested decl.
<case ADDR_EXPR>: Instead of checking if the immediate part
of the ADDR_EXPR changed, check the field changed.
Use recompute_tree_invarant_for_addr_expr instead of unsetting
TREE_INVARIANT.
(convert_local_reference): Set changed to when we

<case ADDR_EXPR>: Instead of checking if the immediate part

Also call recompute_tree_invarant_for_addr_expr on the ADDR_EXPR.
