b7710f8516 [MS Demangler] Re-write the Microsoft demangler.
This is a pretty large refactor / re-write of the Microsoft
demangler.  The previous one was a little hackish because it
evolved as I was learning about all the various edge cases,
exceptions, etc.  It didn't have a proper AST and so there was
lots of custom handling of things that should have been much
more clean.

Taking what was learned from that experience, it's now
re-written with a completely redesigned and much more sensible
AST.  It's probably still not perfect, but at least it's
comprehensible now to someone else who wants to come along
and make some modifications or read the code.

Incidentally, this fixed a couple of bugs, so I've enabled
the tests which now pass.

b81e08b31f [MS Demangler] Print calling convention inside parentheses.
For function pointers, we would print something like

int __cdecl (*)(int)

We need to move the calling convention inside, and print

int (__cdecl *)(int)

This patch implements this change for regular function pointers as
well as member function pointers.

246526b1b4 [MS Demangler] Demangle pointers to member functions.
After this patch, we can now properly demangle pointers to member
functions.  The calling convention is located in the wrong place,
but this will be fixed in a followup since it also affects non
member function pointers.

0bef0a2efc 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-*.
