[PATCH v3 0/3] Add Scripts for Finding Top 25 Executed Functions

[Ahmed Karaman <ahmedkhaledkaraman@gmail.com>]

Greetings,

As a part of the TCG Continous Benchmarking project for GSoC this
year, detailed reports discussing different performance measurement
methodologies and analysis results will be sent here on the mailing
list.

The project's first report is currently being revised and will be
posted on the mailing list in the next few days.*
A section in this report will deal with measuring the top 25 executed
functions when running QEMU. It includes two Python scripts that
automatically perform this task.

This series adds these two scripts to a new performance directory
created under the scripts directory. It also adds a new
"Miscellaneous" section to the end of the MAINTAINERS file with a
"Performance Tools and Tests" subsection.

Previous version of the series:
https://lists.nongnu.org/archive/html/qemu-devel/2020-06/msg06147.html

*UPDATE: Report 1 was published on the mailing list on Monday the 22nd
of June.

Best regards,
Ahmed Karaman

v2->v3:
- Use a clearer "Syntax" and "Example of usage" in the script comment
  and commit message.
- Manually specify the instructions required to run Perf instead of
  relying on the stderr produced by Perf.
- Use more descriptive variable names.
