This adds support for most of the remaining LLVM command line tools using a generic, generated wrapper. The subcommand interface for these is (much) less interesting than our other subcommands, but it gives us a uniform and consistent layer. Note that I structured these as nested sub-sub-commands below an `llvm` subcommand because of an expectation that we will want to add more, and ones that don't use this generic layer. Some concrete future work: - Add the `opt` and `llc` tools as subcommands for easier debugging and experimentation with LLVM IR output from Carbon's toolchain. - Potentially sink `lld` below the `llvm` layer given that it has significantly less user visibility than commands like `clang`. Unfortunately, the current driver subcommand APIs make nested subcommands awkward. I've added a somewhat rough hack here to let the LLVM tools go in, but there are some TODOs that I want to address in a follow-up that works to adjust the structure of this code to be more conducive to nesting like this. Depends on #5048 -- only the last commit should be reviewed here. --------- Co-authored-by: Geoff Romer <gromer@google.com>
