[PATCH][AArch64] Use Cortex A53 rtx costs table in aarch64

[Kyrill Tkachov]

Hi all,

This patch gets the aarch64 backend to use the Cortex A53 costs when tuning for 
that core, instead of using the generic costs. The costs table itself was added 
recently in arm/aarch-cost-tables.h and is shared between the two ports.

Tested aarch64-none-elf on a model.

Ok for trunk?

Thanks,
Kyrill
