Silence the driver warnings, if we see "-w" on the Driver.
Summary:
We can enable warnings after that -w, so the patch might not be 100%
correct.
The problem that triggered this is: we have some amount of tests that
expect 0 warnings (including unit tests for -w), but -w ends up not fully
silencing everything.
