AArch64: Add INITIALIZE_PASS_* macros to AArch64A57FPLoadBalancing.

[gberry]

Summary

These are needed so this pass will produce output when
e.g. -print-after-all is used.

Since we don't need to initialize any pass dependencies (e.g., AliasAnalysis), I don't think we need both the BEGIN and END macros; a singleINITIALIZE_PASS would suffice. However, I don't think it really matters.
