/**
 * @dev OpcodeChecker processes contract code to generate a bitmap of used opcodes.
 *
 * The generated bitmap can be used to enforce whitelisting and blacklisting on contract code.
 * Bit n of the bitmap is set iff opcode n is used. For instance, the presence of the STOP opcode
 * will result in bit 0 of the bitmap being set.
 *
 * A best-effort attempt is made to skip over unreachable data, but there may be false positives.
 * To the extent the checker is written correctly, there are no false negatives.
