Optimize stack map decoding.
We usually read several consecutive varints.
Add helper method optimized for that use case
(ideally reading 8 varints from single load).
This improves app startup by 0.4% (maps,speed).
PMD on golem seems to get around 5% faster.
CodeInfo::Decode on its own is 25% faster.
