Original commit message:

    Avoid disassembling Interpreted Regexp code

    I found that v8 will crash when --print-code is turned on while Regexp
    is interpreted. It crashes when trying to print Relocation info during
    Disassembly. It should probably avoid printing out disassembly when the
    Code object is a bytecode regexp.
