[PATCH][AArch64] Use common rtx cost table structures with arm

[Kyrill Tkachov]

Hi all,

This patch adjusts aarch64 to use the the same rtx cost table struct as arm and 
adds an include for the aarch-cost-table.h file which will include shared cost 
tables.

The rtx costs function is adjusted to use the correct struct and fields.

Tested aarch64-none-elf on a model.

Ok for trunk?

Thanks,
Kyrill

     * config/aarch64/aarch64.c: Include aarch-cost-tables.h.
     (generic_rtx_cost_table): Remove.

     * config/aarch64/aarch64-protos.h (tune_params): Use cpu_cost_table for
     insn_extra_cost.
