Andrea Di Biagio d10ed7c8d7 Reapply "[llvm-mca] Return the total number of cycles from method Pipeline::run()." 
This reapplies r347767 (originally reviewed at: https://reviews.llvm.org/D55000)
with a fix for the missing std::move of the Error returned by the call to
Pipeline::runCycle().

Below is the original commit message from r347767.

If a user only cares about the overall latency, then the best/quickest way is to
change method Pipeline::run() so that it returns the total number of cycles to
the caller.

When the simulation pipeline is run, the number of cycles (or an error) is
returned from method Pipeline::run().
The advantage is that no hardware event listener is needed for computing that
latency. So, the whole process should be faster (and simpler - at least for that
particular use case).
