            Bug ID: 153080
           Summary: Use DFG
                    Graph::binary/unaryArithShouldSpeculateInt32/MachineIn
                    t() functions consistently.
    Classification: Unclassified

           Version: WebKit Local Build
          Hardware: Unspecified
                OS: Unspecified
            Status: NEW
          Severity: Normal

We currently have Graph::mulShouldSpeculateInt32/machineInt() and Graph::negateShouldSpeculateInt32/MachineInt() functions which are only used by the ArithMul and ArithNegate nodes.  However, the same tests need to be done for many other arith nodes in the DFG.  This patch renames these functions as Graph::binaryArithShouldSpeculateInt32/machineInt() and Graph::unaryArithShouldSpeculateInt32/MachineInt(), and uses them consistently in the DFG.
