Kostya Kortchinsky 4adf24502e [scudo] Add verbose failures in place of CHECK(0)
Summary:
The current `FailureHandler` mechanism was fairly opaque with regard to the
failure reason due to using `CHECK(0)`. Scudo is a bit different from the other
Sanitizers as it prefers to avoid spurious processing in its failure path. So
we just `dieWithMessage` using a somewhat explicit string.

Adapted the tests for the new strings.

While this takes care of the `OnBadRequest` & `OnOOM` failures, the next step
is probably to migrate the other Scudo failures in the same failes (header
corruption, invalid state and so on).
