Hi apazos, mcrosier, t.p.northover,

We havd found that the FP Load Balancing pass designed for Cortex-A57 does not hurt Cortex-A53 performance. It would be helpful in the scenario where "-mcpu=cortex-a53" is used for Cortex-A57 hardware.

Will make this pass and it's test case target agnostic in the next patch.
