Previously, minifier testing injected faults by injecting extra code
into the repro scripts, and then ensuring this code got propagated to
all subsequent subprocess calls. This was not only quite complicated,
but also induced a big slowdown on the minifier, because to inject the
faults, you had to import torch._inductor, which would cause the
compilation threads to immediately get initialized before you even got
to do anything else in the repro script.
This new approach fixes this problem by incorporating the fault
injection into "prod" code. Essentially, for inductor fault injection
we introduce some new config flags that let you "configure" Inductor to
be buggy; for Dynamo fault injection we just permanently keep the buggy
testing backends registered. This is MUCH simpler: we only have to
propagate the buggy config (which is something we're already doing),
and it saves the minifier scripts from having to immediately initialize
inductor on entry.
Also, I enable the test for Triton runtime errors, now that tl.assert_device is here.
