re PR middle-end/82569 (failure in 177.mesa cpu2000 test case after r253530)
PR middle-end/82569
* tree-outof-ssa.h (always_initialized_rtx_for_ssa_name_p): Delete.
* expr.c (expand_expr_real_1) <expand_decl_rtl>: Revert latest change.
* loop-iv.c (iv_get_reaching_def): Likewise.
* cfgexpand.c (expand_one_ssa_partition): Initialize the RTX if the
variable is promoted and the partition contains undefined values.
