Reduced:
```
int celt_encode_with_ec_st, celt_encode_with_ec_st_0,
    celt_encode_with_ec_nbFilledBytes;
void ec_enc_shrink();
void celt_encode_with_ec_max_allowed() {
  int nbAvailableBytes = celt_encode_with_ec_nbFilledBytes;
  if (celt_encode_with_ec_st && celt_encode_with_ec_st_0)
    if (celt_encode_with_ec_max_allowed < nbAvailableBytes)
      ec_enc_shrink();
}
