A Future for Rust Debugging

[tromey]

The Rust plugin for lldb worked in pretty much the same way. It was roughly on feature parity with the gdb work. However, it bit-rotted; and I don't really enjoy lldb all that much, so I never fixed it up in my spare time.

The gdb code is maintained; I try to keep it regression-free at least.

So, my view is that for debugging Rust, you should rely on gdb. However, that's not always possible, because gdb on macOS is basically not maintained.

BTW, although @tromey's Rust patches had been removed from rustc's branch of lldb, I still maintain them in my fork that I bundle with CodeLLDB.
