name: Sanitized CI

## Running these jobs is slow (over ~1 hour, sometimes even 2)
## so we run them only when there is a chance that the generated
## C code could have changed, or for some critical vlib modules,
## like `builtin`, `os`, `sync`, where they have demonstrated
## their usefulness by catching actual very hard to find bugs.
## The cost of this selective running is delayed feedback when
## there are bugs in other V modules.
## The positive is *much faster CI runs* for most V contributors,
## that make PRs that are not concerning V itself, or the critical
## V modules.
