[PATCH] Add some natvis visualizers for llvm::Value and llvm::Type

[Zachary Turner]

Hi aaron.ballman,

Figures out the derived type of an llvm::Type, and adds an entry to the watch window that automatically casts to the derived type.

I'm not very good at writing these, so I'm not sure if this is the best possible way to express this.
