CI: create a bench job
The main idea is compare performance between HEAD master and the current branch.
- Goal: find regressions
For example: (probably with a few categories/groups to catch regressions restricted to some area)
Analisys
master ████ (1.4 min)
current ██████ (2.0 min)
Result: noticeable performance loss
PS: I'm not sure if the profiler can do bench and output the duration of a task/test.
