tcg-ppc64: Use TCGType throughout compares
The optimization/bug being fixed is that tcg_out_cmp was not applying the right type to loading a constant, in the case it can't be implemented directly. Rather than recomputing the TCGType enum from the arch64 bool, pass around the original TCGType throughout.
