[X86][BtVer2] Update the WriteLoad latency.

[andreadb]

Summary

r327630 introduced new write definitions for float/vector loads.
Before that revision, WriteLoad was used by both integer/float (scalar/vector) load. So, WriteLoad had to conservatively declare a latency to 5cy. That is because the load-to-use latency for float/vector load is 5cy.

Now that we have dedicated writes for float/vector loads, there is no reason why we should keep the latency of WriteLoad to 5cy. At the moment, WriteLoad is only used by scalar integer loads only; we can assume an optimstic 3cy latency for them.
This patch changes that latency from 5cy to 3cy, and regenerates the affected scheduling/mca tests.

Can we remove this FIXME?

[andreadb]

Removed FIXME.

[RKSimon]

LGTM - folded scalar loads already use the 3cy load latency.
