[llvm-dev] [cfe-dev] Emiting linkage names for Types to Debuginfo (C++ RTTI support in GDB/LLDB)

It could, but mangled names can be very long and we need to consider
whether the additional size cost is worth it under various conditions.
For example, does this type matching work when a program is compiled
with `-fno-rtti`?  (Clang itself is compiled this way by default.)
