I agree, since currently we're calculating true size separately in LongJmp for aarch64 like 
`DotAddress = alignTo(DotAddress, Func->getConstantIslandAlignment());
  DotAddress += Func->estimateConstantIslandSize();`

It would be better to incorporate this code to BF-specific size calculation function
