Description Yusuke Suzuki 2020-04-17 04:34:52 PDT 
We only have 9 opcode space up to 256. If it exceeds 256, JSC is broken.
Even if we support two-level indirection mechanism to offer larger space of opcode, we know that this type of opcode offers significantly slower performance. (I know that in some bug).
We should remove unnecessary things from Bytecodes.
