[llvm-commits] Enable -Wcovered-switch-default in our builds

[Daniel Dunbar]

Hi Rafael,

It turns out that your configure check doesn't work as intended with
Clang, because Clang doesn't error out on unknown warning options.

This makes the build have a lot of warning spew when building with an
older version of Clang.

Can you see about fixing CXX_FLAG_CHECK to handle this case?
