    i965/gs: Check newly-generated GS-out VUE map against correct stage

    Previously, we compared our new GS-out VUE map to the existing *VS*-out
    VUE map, which is bogus.

    This would mostly manifest as redundant dirty flagging where the GS is
    in use but the VS and GS output layouts differ; but there is a scary
    case where we would fail to flag a GS-out layout change if it happened
    to match the VS-out layout.
