Add test function with EVM circuit stats

[ed255]

This is a little utility (in the form of a test function) that prints to stdout a table with all the implemented states and their responsible opcodes with the following stats:

• height: number of rows used by the execution state
• gas: gas value used for the opcode execution
• height/gas: ratio between circuit cost and gas cost

The idea of this utility is to quickly check which are the worst case opcodes in terms of rows VS gas cost.

Here's the current table:

LGTM !!

[ChihChengLiang]

LGTM. Great script!

[ChihChengLiang]

@ed255 The row listed in @han0110's table is 34 access/3 gas.
But the table listed by this PR is 5 rows/15 gas = 0.3333.
Do we know what causes the difference?

[han0110]

^{34 access}/_{3 gas} goes to State circuit, the table added in this PR is for EVM circuit, so that's why it's so different (so actually after Keccak, State circuit would be the next bottleneck in regard to gas capacity without satisfied solution for now.)
