Add a Microsoft Demangler.
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-*. Differential Revision: https://reviews.llvm.org/D49552 llvm-svn: 337584
