See "discussion": https://discourse.llvm.org/t/rfc-dexter-feature-removals/60462 This patch removes the builder functionality from Dexter, as it is an active maintenance burden and is no longer required since Dexter is being invoked by other test runners that can handle the build step better, and there has been no objection that it is still needed.
