We're shipping a rust-enabled lldb, but the "lldb" executable is not installed into the "bin" directory by rustup. See the discussion in https://github.com/rust-lang-nursery/rustup.rs/pull/1492 for background on this decision. There, we agreed to have rust-lldb prefer the rust-enabled lldb if it is installed. This patch changes dist.rs to put lldb into rustlib, following what was done for the other LLVM tools in #53955, and then fixes rust-lldb to prefer that lldb, if it exists. See issue #48168
