jsimd_can_encode_mcu_AC_*(): Remove useless checks

Browse Source 
These were necessary for the first iteration of the feature (see #46),
which provided a different C front end for the SIMD version of the
function.  The final version of the feature uses a common C front end
for both SIMD and non-SIMD implementations, so these checks are no
longer necessary.

Closes #231
