Write a C ++ name demangle Function

Of course it is not decoded by yourself, but some gods do this:

Http://hi.baidu.com/avengine/blog/item/9b7147a94c78c4fc1e17a2f7.html

And this

Http://sourceforge.net/projects/php-ms-demangle/

It is copied from wine.

This is to solve the problem that GCC typeinfo: name does not return the original name.

GCC output:
St6vectorisssaissee
STD: vector <STD: String, STD: Allocator <STD: String>

The typeinfo name of VC is after demangle, and the output is
Class STD: vector <class STD: basic_string <char, struct STD: char_traits <char>,
Class STD: Allocator <char>, class STD: Allocator <class STD: basic_string <char,
Struct STD: char_traits <char>, class STD: Allocator <char >>>
Class STD: vector <class STD: basic_string <char, struct STD: char_traits <char>,
Class STD: Allocator <char>, class STD: Allocator <class STD: basic_string <char,
Struct STD: char_traits <char>, class STD: Allocator <char >>>
