MCTargetOptionsCommandFlags.inc and CommandFlags.inc are headers which contain cl::opt with static storage. These headers are meant to be incuded by tools to make it easier to parametrize codegen/mc. However, these headers are also included in at least two libraries: lldCommon and handle-llvm. As a result, when creating DYLIB, clang-cpp holds a reference to the options, and lldCommon holds another reference. Linking the two in a single executable, as zig does[0], results in a double registration. This patch explores an other approach: the .inc files are moved to regular files, and the registration happens on-demand through static declaration of options in the constructor of a static object.
