Don't use intrinsics when they are slower.

Browse Source 
More thorough en-/decoding tests show that sometimes the functions
that use intrinsics are slower (or not really faster) than old
plain C functions.

After this patch the encoder doesn't use these new functions
when their usefulness is questionable.
