Extended Description

Meta ticket covering issues with the x86 scheduler models, which currently include:

X86ScheduleAtom.td
X86SchedSandyBridge.td
X86SchedHaswell.td
X86ScheduleSLM.td
X86ScheduleBtVer2.td

Including incorrect latency/throughput values and resources.

Also covers possible improvements to how we can use the schedulers to improve performance (e.g. use in the machine combiner for better instruction selection).
