* expr.h (expand_expr): Make it a macro, not a function.
(expand_expr_real): New function.
* expr.c (store_expr): Adjust logic for deciding whether or not to
copy the value returned by expand_expr.

(expand_expr_real): ... this. Add alt_rtl parameter. Adjust
calls to language hooks.

(last_expr_alt_rtl): Likewise.
(expand_expr_stmt_value): Set last_expr_alt_rtl.
(clear_last_expr): Clear it.
(expand_end_stmt_expr): Set RTL_EXPR_ATL_RTL.
(expand_end_bindings): Save and restor last_expr_alt_rtl.
* tree.def (RTL_EXPR): Give it an additional operand.
