Sphinx-based clang man pages Summary: This diff introduces .rst files, Sphinx config, and a CMake target for building clang man pages. This will deprecate the existing .pod- based man page, and will integrate nicely with CMake. This diff does not remove the existing man page; that will be done in a follow-up once packagers have had a chance to react to the change. For now, only clang(1) has been done; others can be added over time by dropping additional files into the docs/CommandGuide directory. The index page for CommandGuide has been copied from LLVM's docs/CommandGuide. The man page itself is mostly the same, with a few minor cosmetic changes. The only major change is the SYNOPSIS section. I was unable to get .rst/Sphinx produce the same style as in the existing man page. Instead, I changed it to match the LLVM tools' relatively simple style. To build the man pages, use the "docs-clang-man" target if building with CMake. Otherwise, use "make -f Makefile.sphinx man".

Clang "man" pages
-----------------
The following documents are command descriptions for all of the Clang tools.
These pages describe how to use the Clang commands and what their options are.
Note that these pages do not describe all of the options available for all
tools. To get a complete listing, pass the ``--help`` (general options) or
``--help-hidden`` (general and debugging options) arguments to the tool you are
interested in.

[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.
