I believe there is some work being done on that already <
http://lists.llvm.org/pipermail/lldb-dev/2018-January/013186.html>, but I'm
not sure what's the current state of it. Also, in the default
configuration, LLDB will use lllvm::itaniumDemangle for demangling
(although there is a build option to use cxa_demangle).
