tcg-ppc64: Use TCGType throughout compares

Browse source 
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.
