Forcing -Werror and other warnings means that the test suite isn't actually testing what most people are seeing in their code -- it seems better and less arbitrary to compile these tests as close as possible to the compiler default instead. Removing -Werror also means that we get to differentiate between diagnostics that are errors and those that are warnings, which makes the test suite more precise.
