expr.c (expand_expr, [...]): Make TARGET_EXPRs redoable for UNSAVE_EXPR.
* expr.c (expand_expr, cond TARGET_EXPR): Make TARGET_EXPRs
redoable for UNSAVE_EXPR.
* stmt.c (expand_decl_cleanup): Wrap the cleanup in an UNSAVE_EXPR
to that we can redo it.
* tree.c (unsave_expr_now): Handle TARGET_EXPRs fully now.
* tree.def (TARGET_EXPR): Add a third field so that TARGET_EXPRs
are redoable.
