1- subst: use fast RgX_affine function to compute P(a*x+b)

+ fix RgX_affine (assumed b t_INT)
+ let RgX_tranlate call ZX_translate if possible
+ let ZX_translate do a simple copy if b = 0 (very frequent in bench!)

The patch is correct but breaks the lfun bench by exposing an independent
bug in nfcompositum (invalid t_POL whose coefficients are t_POL in
variables of higher priority). To be fixed in a followup commit.
