            Bug ID: 36673
           Summary: [llvm-mca][MC] Expose methods
                    `computeInstrRThroughput` and `computeInstrLatency` to
                    MCSchedModel.

Currently, both methods are accessible from the TargetSchedModel interface.

It would be nice to have those methods accessible from MCSchedModel, so that
llvm-mca can use them to compute the "max latency" and the reciprocal
throughput.

Currently, llvm-mca uses its own logic to compute latency and throughput. We
could get rid of that logic and simplify the code if only those two methods
were accessible. In llvm-mca, it would allow to fully decouple the SummaryView
logic from the Backend.
