The coverage format version we use is automatically set to whatever the latest version LLVM has. This resulting in us outputting version 6 as our format without having made the changes necessary to reflect the new format. Update the emission logic to take account for [the new changes in version 6][1] (we need to include the current working directory as the first element of the list of files we output). Additionally, add a `static_assert` so we don't get caught out by version bumps in the future. Note we can't pin our version, as it must stay in sync with the version Clang is using.
