Fix rvrp-abs-3 which recognizes that the IMAGPART_EXPR result of an builtin ADD/SUB overflow call is actully a boolean flag.. so its range is [0,1].
tweaked the op_cast routine to handle this better by FIRSt trying the cast rhs to lhs and back trick if that fails,then we look at the weird masking of -1. obscure enough? lookit the code.
