[PATCH] D52932: [MCSched] Bind PFM Counters to the CPUs instead of the SchedModel.

Sorry for late reply!

It looks like we need to find a way to still embed this information in MCExtraProcessorInfo but allow for different CPUs PFM mappings.

One of the aims for PR39165 was to make it possible for llvm-exegesis to be run on CPUs with declared PFMs but without a model - allowing a report on raw resource usage for an instruction and to help create the model from scratch. @courbet @gchatelethow do you think this would be useful? Is it still an aim of llvm-exegesis to create models from scratch or just report on existing models?

Can you easily attach PFM mappings to the GenericModel/GenericPostRAModel?
