Can not operate "shiftR" on Int

[Alaya-in-Matrix]

module Learn where 
import CLaSH.Prelude

div2 = (flip shiftR) 1

topEntity :: Int -> Int
-- topEntity :: Unsigned 8 -> Unsigned 8
topEntity = div2

I intended to use shiftR to replace div, but found that code use shiftR failed to generate verilog code. However, if I change topEntity::Int->Int to topEntity::Unsigned 8 -> Unsigned 8, everything goes well.

Thanks for the report. Indeed, I forgot to add primitives for those functions as I almost never work with Int myself.
