            Bug ID: 205553
           Summary: [JSC] Compact Bytecodes more by emitting 1-byte Opcode
           Product: WebKit
           Version: WebKit Nightly Build
          Hardware: Unspecified
                OS: Unspecified
            Status: NEW
          Severity: Normal
          Priority: P2
         Component: JavaScriptCore
          Assignee: webkit-unassigned at lists.webkit.org
          Reporter: ysuzuki at apple.com

When using op_wide16 / op_wide32, we are emitting Opcode in 16bit / 32bit. But Opcode always fit in 8bit.
We should emit 8bit opcode instead, I think this makes Bytecode further compact, and this is nice since bytecode Opcode access becomes alignment-free.
