core/vm: reverse bit order in bytes of code bitmap ( #24120 )
...
* core/vm: reverse bit order in bytes of code bitmap
This bit order is more natural for bit manipulation operations and we
can eliminate some small number of CPU instructions.
* core/vm: drop lookup table

All code outside of cmd/ is licensed as LGPL. The headers
now reflect this by calling the whole work "the go-ethereum library".

core/vm: improve JUMPDEST analysis
...
* JUMPDEST analysis is faster because less type conversions are performed.
* The map of JUMPDEST locations is now created lazily at the first JUMP.
* The result of the analysis is kept around for recursive invocations
through CALL/CALLCODE.
Fixes #1147
