Florian Hahn 1ccc49924a [AArch64] Add getCFInstrCost, treat branches as free for throughput. ... D79164/2596da31740f changed getCFInstrCost to return 1 per default. AArch64 did not have its own implementation, hence the throughput cost of CFI instructions is overestimated. On most cores, most branches should be predicated and essentially free throughput wise. This restores a 9% performance regression on a SPEC2006 benchmark on AArch64 with -O3 LTO & PGO. This patch effectively restores pre 2596da3174 behavior for AArch64 and undoes the AArch64 test changes of the patch.
