Fixed bugs in VC9Demangler

[AnkeStrasberg]

I fixed some bugs in VC9Demangler and attached the new file (compare to 1e3bd66 from 27 Mar 2015).
I verified that DemanglingTest still runs successfully and I created a new test class DemanglingTestMsvc and three resource files containing mangled an unmangled names taken from depends.exe. There are two resource files containing the names of some functions that I defined using a dll project created with Visual Studio 2015. I think Visual Studio 2008 should work, too. I attached the code file I wrote.
The third resource file contains functions from msvcr100.dll which is installed on my computer.
I would be glad if you added my changes to the project!
