Summary:
This patch eliminates some redundancy in iterating across Listeners for the
Instruction and Stall HWEvents, by introducing a template onEvent routine.
This change was suggested by @courbet in https://reviews.llvm.org/D48576. I
hope that this patch addresses that suggestion appropriately. I do like this
change better than what we had previously.

This will allow us to share the logic that computes the block throughput with
other views.

This patch implements the "block reciprocal throughput" computation in the
SummaryView.
The block reciprocal throughput is computed as the MAX of:
- NumMicroOps / DispatchWidth
- Resource Cycles / #Units (for every resource consumed).
The block throughput is bounded from above by the hardware dispatch throughput.
That is because the DispatchWidth is an upper bound on how many opcodes can be part
of a single dispatch group.
The block throughput is also limited by the amount of hardware parallelism. The
number of available resource units affects how the resource pressure is
distributed, and also how many blocks can be delivered every cycle.

We've been running doxygen with the autobrief option for a couple of
years now. This makes the \brief markers into our comments
redundant. Since they are a visual distraction and we don't want to
encourage more \brief markers in new code either, this patch removes
them all.

make the SummaryView independent from the Backend. NFCI
Since r327420, the tool can query the MCSchedModel interface to obtain the
reciprocal throughput information.
As a consequence, method `ResourceManager::getRThroughput`, and
method `Backend::getRThroughput` are no longer needed.
This patch simplifies the code by removing the custom RThroughput computation.
This patch also refactors class SummaryView by removing the dependency with
the Backend object.
No functional change intended.
