llvm-undname: Make demangling of MD5 names more robust Demangler::parse() for MD5 names would: 1. Put all remaining text into the MD5 name sight unseen 2. Not modify MangledName This meant that if the demangler recursively called parse() (e.g. in demangleLocallyScopedNamePiece()), every recursive call that started on an MD5 name would add all remaining bytes to the output buffer but only advance the input by a byte. For valid inputs, MD5 types are never (well, see comments for 2 exceptions) nested, but for invalid input this could cause memory use quadratic in the input size. llvm-svn: 361744

; These tests are based on clang/test/CodeGenCXX/mangle-ms-md5.cpp
[MS Demangler] Don't fail on MD5-mangled names. When we have an MD5 mangled name, we shouldn't choke and say that it's an invalid name. Even though it's impossible to demangle, we should just output the original name. llvm-svn: 339891
