This is useful for understanding how our demangler processes
back references and for investigating issues related to
back references. But it's a feature only useful for debugging
the demangling process itself, so I'm marking it hidden.

If an error occurs and we write it to stderr, it could appear
before we wrote the mangled name which we're undecorating.
By flushing stdout first, we ensure that the messages are always
sequenced in the correct order.

This adds initial support for a demangling library (LLVMDemangle)
and tool (llvm-undname) for demangling Microsoft names. This
doesn't cover 100% of cases and there are some known limitations
which I intend to address in followup patches, at least until such
time that we have (near) 100% test coverage matching up with all
of the test cases in clang/test/CodeGenCXX/mangle-ms-*.
