Simon Pilgrim 8a83f16ccd [X86][SandyBridge] SBWriteResPair +5cy Memory Folds
As mentioned on D44647, this patch increases the default memory latency to +5cy , which more closely matches what most custom cases are doing for reg-mem instructions.

I've bumped LoadLatency, ReadAfterLd and WriteLoad values to 5cy to be consistent.

As Sandy Bridge is currently our default generic model, this affects a lot of scheduling tests...
