Evaluate Profile-Guided Optimization (PGO)

[zamazan4ik]

According to my tests, Profile-Guided Optimization (PGO) helps with optimizing to a lot of software (including OS like Linux and Windows - link). I think it's worth trying to apply PGO to ToaruOS.

We need to perform PGO benchmarks on ToaruOS. If it shows improvements - add a note to the documentation about possible improvements to ToaruOS's performance with PGO. After that, providing an easier way (e.g. a build option) to build scripts with PGO can be useful for the maintainers and end-users too. Also, applying PGO on ToaruOS can be used as an example for other operating systems.

If anyone already did PGO benchmarks with ToaruOS - would be awesome to see the results.
