I noticed that HWASAN forces compilation of position independent object files (this happens in `SanitizerArgs.cpp`). This means
that uninstrumented objects/libraries will likely also be position independent, because linking PIE vs non-PIE is problematic.

That said we can probably use ordinary ifuncs in the same way it's done with `__hwasan_shadow`
Your thoughts?
