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

3f047be5aa all: update license headers to distiguish GPL/LGPL
All code outside of cmd/ is licensed as LGPL. The headers
now reflect this by calling the whole work "the go-ethereum library".

ea2718c946 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
