support
Reimplement select in terms of SEL *We would really like to support but we need to prove that the add doesn t need to overflow between the two bit chunks *Implement pre post increment support(e.g. PR935) *Implement smarter const ant generation for binops with large immediates. A few ARMv6T2 ops should be pattern matched
