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

[Zachary Turner]

FWIW I actually wrote one that's used for anyone working on Chromium.  It's
a Visual Studio plugin, and unfortunately you need a fairly significant
amount of plumbing to get it up and running, but once it's there it's not
too bad to add new stuff to.  You still wouldn't want to do it for every
little thing, as for simpler cases natvis is still superior.  But it does
give you quite a bit more control over how things are displayed.  If you're
interested, the project is here:

https://github.com/chromium/vs-chromium/

and the stuff of interest, after you cut through all the boilerplate, is in
here: https://github.com/chromium/vs-chromium/tree/master/src/DkmIntegration

I've thought about doing the same type of thing here, but just getting
through all the boiler plate stuff to a simple visualizer up would be a day
or two.
