[PATCH 0/8] MR492: Enhancements for C++ symbols undecoration

[eric pouech (＠epo)]

This series implements a couple of enhancements to symbol undecoration in
msvcrt:
- more C++ constructs are correctly supported (pointer to member,
  constructors/destructors from template class,
  non-type function pointer template parameter...)
- some internal cleanups & simplification (most of them based on
  revamped helper to build up the undecorated C++ symbols)
