[cfe-dev] Clang static analyzer checkers

[Artem Dergachev via cfe-dev]

This functionality is under `#ifndef NDEBUG`, removed from builds 
without asserts. I don't instantly understand the good reason for that 
though. Even if there is one, we should mention it on the website 
(http://clang-analyzer.llvm.org/checker_dev_manual.html#visualizing).

There are no dependencies involved; all clang has to do is to write a 
plain-text .dot file by hand and system() a universal viewer command 
(eg. xdg-open on linux).
