    Add a MathFloor stub generated with TurboFan · abc35080
    danno authored
    This stub will be used as the basis of a Math.floor-specific CallIC to
    detect and track calls to floor that return -0.
    
    Along the way:
    - Create a TurboFanCodeStub super class from which the StringLength and
    MathRound TF stubs derive.
    - Fix the ugly hack that passes the first stub parameter as the "this"
    pointer in the the TF-compiled JS function.
    - Fix bugs in the ia32/x64 disassembler.
