[REPORT] [GSoC - TCG Continuous Benchmarking] [#8] QEMU Nightly Performance Tests

Hi everyone,

QEMU currently lacks a system for measuring the performance of targets
automatically. The previous reports introduced different tools and
methods for locating performance regressions, but all of them had to
be manually executed by the user when needed.

This report devises a new nightly tests system that runs automatically
each night. After the execution is completed, it sends a report to the
QEMU mailing list with the performance measurements of seventeen
different QEMU targets, and how these measurements compare to
previously obtained ones.

The system is now scheduled to execute daily, and starting from
tonight, the results will be sent to the mailing list.
