[ARM] Pass architecture to TargetParser defaulting to cope with API change

[bsmith]

Summary

The TargetParser API to get the default FPU and extensions will change in D14661, this is so it can fall back to the architecture in case of a generic CPU. This patch adjusts calls to the changed functions to pass in the correct information.
