Hi rob.lougher, andreadb, RKSimon,

This is a first pass at a scheduling model for Jaguar. It's structured largely on the existing SandyBridge and SLM sched models. 

Using this model, in addition to turning on the PostRA scheduler, results in some perf wins on internal and 3rd party benchmarks. There's not much difference in LLVM's test-suite benchmarking subset of tests.
