Analyze opcode table

[Arkenan]

We currently have an opcode table in LEVM to redirect from opcode to implementation. We don't know if this is a jump or a call table internally. We need to make that analysis and, in case we are using a call table, evaluate using a jump table and see if we observe improvements.

According to @azteca1998 this is, in fact, a call table. We will investigate if we can turn it into a jump table and measure it.
