As we upgrade LLVM, we need to upgrade LLDB and drop local cherry-picked
patches.

LLDB uses liblldb.so path relative logic internally.

Python scripting is not something that we want, if anything we might
want to use Lua scripting but it is not a priority in base.

But as there is planned an LLVM upgrade, we shall upstream something
alternative to the liblldb.so path relative logic and avoid local
patches. Michal, could you have a look into this?
