A new on by default warning in clang aims to flag cases where a const variable or field is not initialized and has no default value (i.e., not static or thread local). The field version of the warning triggers in several places within the kernel that are not problematic so it is disabled in the first patch. The variable version of the warning only triggers in one place, the typecheck() macro, so I opted to silence it in that one place to keep it enabled until it can be proved to be problematic enough to disable it.
