now that predicates have a decent abstraction layer on them, introduce a new

kind of predicate: one that is specific to imm nodes.  The predicate function
specified here just checks an int64_t directly instead of messing around with
SDNode's.  The virtue of this is that it means that fastisel and other things
can reason about these predicates.
