Hexagon (target/hexagon) Move new_pred_value to DisasContext

Browse source 
The new_pred_value array in the CPUHexagonState is only used for
bookkeeping within the translation of a packet.  With recent changes
that eliminate the need to free TCGv variables, these make more sense
to be transient and kept in DisasContext.
