Roman Lebedev d23b6831de [X86][Znver1] Specify Register Files, RCU; FP scheduler capacity.
Summary:
First off: i do not have any access to that processor,
so this is purely theoretical, no benchmarks.

I have been looking into b**d**ver2 scheduling profile, and while cross-referencing
the existing b**t**ver2, znver1 profiles, and the reference docs
(`Software Optimization Guide for AMD Family {15,16,17}h Processors`),
i have noticed that only b**t**ver2 scheduling profile specifies these.

Also, there is no mca test coverage.

Roman Lebedev 9ddf128f79 [MCA] Add -summary-view option
Summary:
While that is indeed a quite interesting summary stat,
there are cases where it does not really add anything
other than consuming extra lines.

Declutters the output of D48190.
