I agree that the average developer will not have much use of the possibility of accessing Wasm locals and globals. I also understand that Wasm locals and global are a very specific, Wasm-only concept and that adding this concept in LLVM core is not pertinent. However for people working on the inner workings of Wasm (like me), it may be very useful. I'm not sure it belongs to this PR but implementing support for accessing Wasm locals/globals in the future (using perhaps a command like `language wasm`) seems an interesting thing to do to complete the debugging experience on Wasm with lldb.

What I'm wondering is, does these potential added commands have an impact on this PR ? Or can we imagine commands that will send a specific, Wasm-only request to the debugging server to get the values of the variables without using the implementation of locals and globals of this PR ?
