Jonas Devlieghere b48447a1d6 [diagtool] Add diagtool to install target.
Although not very well known, diagtool is an incredibly convenient
utility for dealing with diagnostics.
Particularly useful are the "tree" and "show-enabled" commands:

 - The former prints the hierarchy of diagnostic (warning) flags and
   which of them are enabled by default.
 - The latter can be used to replace an invocation to clang and will
   print which diagnostics are disabled, warnings or errors.
   For instance: `diagtool show-enabled -Wall -Werror /tmp/test.c` will
   print that -Wunused-variable (warn_unused_variable) will be treated as
   an error.

This patch adds them to the install target so it gets shipped with the
LLVM release. It also adds a very basic man page and mentions this
change in the release notes.

// C Language Family Front-end
//===----------------------------------------------------------------------===//

Welcome to Clang.  This is a compiler front-end for the C family of languages
(C, C++, Objective-C, and Objective-C++) which is built as part of the LLVM
compiler infrastructure project.

Unlike many other compiler frontends, Clang is useful for a number of things
beyond just compiling code: we intend for Clang to be host to a number of
different source-level tools.  One example of this is the Clang Static Analyzer.

If you're interested in more (including how to build Clang) it is best to read
the relevant web sites.  Here are some pointers:
