Move the DiagnosticRenderer and its dependents to using FullSourceLocs
instead of a SourceLocation and SourceManager pointer. The changeset is
rather large but entirely mechanical.

This is step one to allow DiagnosticRenderer to take either
llvm::SMLocs or clang::SourceLocations.

With this patch, one can configure a BufWrite hook that will make the
clang-format integration compute a diff of the current buffer with the file
that's on disk and format all changed lines. This should create a
zero-overhead auto-format solution that doesn't require the file to
already be clang-format clean to avoid spurious diffs.

When -no-canonical-prefixes option is used and argv0 contains only
a program name, we need to do a PATH lookup to get an executable path,
otherwise the return value won't be a valid path and any subsequent
uses of it (e.g. when invoking -cc1) will fail with an error.

This patch fixes PR9576.

Most of libc++'s header files don't use extension. This prevents
using git-clang-format on them, which is frustrating.

This patch allows empty extensions to be passed using either
the --extensions option, or the clangformat.extensions git-config

These options control the behaviour of the compression of debug info
sections on ELF targets.  Our behaviour slightly diverges from the
behaviour of GCC.  `-gz` maps to the `-compress-debug-sections` rather
than `-compress-debug-sections=zlib` or
`-compress-debug-sections=zlib-gnu`.  This small divergence allows us to
be compatible across versions of binutils (=zlib support was introduced
in 2.26, while earlier versions only support =zlib-gnu).  This also
allows users to not have to worry about the version of the assembler
they may be using if they are not using the IAS.  Previously, users
would have had to go through the internal option
`-compress-debug-sectionss` and pass that through to the assembler,
which is no longer needed.

[libclang] Introduce a new parsing option 'CXTranslationUnit_SingleFileParse' that puts preprocessor in a mode for parsing a single file only.

This is useful for parsing a single file, as a fast/inaccurate 'mode' that can still provide declarations from the file, like the classes and their methods.

This is tied with the LLVM side of the change to expose the debug
information compression types to clang.  We now track the compression
type as an enumeration rather than a boolean.  We still use the same
value (GNU) that we did previously.  This is in preparation to support
passing down the compression type and switch it based on the command
line.

Summary:
Other llvm tools display their registered targets when showing version
information, but for some reason clang has never done this.

To support this, D33899 adds the llvm parts, which make it possible to
print version information to arbitrary raw_ostreams.  This change adds
a call to printRegisteredTargetsForVersion in clang's PrintVersion, and
adds a raw_ostream parameter to two other PrintVersion functions.

A suspended translation unit uses significantly less memory but on the
other side does not support any other calls than
clang_reparseTranslationUnit to resume it or
clang_disposeTranslationUnit to dispose it completely.

This helps IDEs to reduce the memory footprint. The data that is freed
by a call to clang_suspendTranslationUnit will be re-generated on the
next (re)parse anyway. Used with a preamble, this allows pretty fast
resumption of the translation unit for further use (compared to disposal
of the translation unit and a parse from scratch).

The scan-build script provided by clang can be used to detect defects in
code in the compile time. However, we discovered that the
"--target=<value>" flag in clang is not properly handled by this script,
which results in failures when analyzing projects that have used this
flag in their makefile.

This single line of change allows scan-build script to properly handle
the "--target=<value>" flag.

This is recommit of r302775, reverted in r302777 due to a fail in
clang-tidy. Original mesage is below.

Now if clang driver is given wrong arguments, in some cases it
continues execution and returns zero code. This change fixes this
behavior.

The fix revealed some errors in clang test set.

File test/Driver/gfortran.f90 added in r118203 checks forwarding
gfortran flags to GCC. Now driver reports error on this file, because
the option -working-directory implemented in clang differs from the
option with the same name implemented in gfortran, in clang the option
requires argument, in gfortran does not.

In the file test/Driver/arm-darwin-builtin.c clang is called with
options -fbuiltin-strcat and -fbuiltin-strcpy. These option were removed
in r191435 and now clang reports error on this test.

File arm-default-build-attributes.s uses option -verify, which is not
supported by driver, it is cc1 option.

Similarly, the file split-debug.h uses options -fmodules-embed-all-files
and -fmodule-format=obj, which are not supported by driver.

Other revealed errors are mainly mistypes.

ASTImporter has some bugs when it's importing types 
that themselves come from an ExternalASTSource. This 
is exposed particularly in the behavior when 
comparing complete TagDecls with forward 
declarations. This patch does several things:

- Adds a test case making sure that conflicting 
  forward-declarations are resolved correctly;
- Extends the clang-import-test harness to test 
  two-level importing, so that we make sure we 
  complete types when necessary; and
- Fixes a few bugs I found this way. Failure to 
  complete types was one; however, I also discovered 
  that complete RecordDecls aren't properly added to 
  the redecls chain for existing forward 
  declarations.

The intent for an explicit module build is that the diagnostics produced within
the module are those that were configured when the module was built, not those
that are enabled within a user of the module. This includes diagnostics that
don't actually show up until the module is used (for instance, diagnostics
produced during template instantiation and weird cases like -Wpadded).

We serialized and restored the diagnostic state for individual warning groups,
but previously did not track the state for flags like -Werror and -Weverything,
which are implemented as separate bits rather than as part of the diagnostics
mapping information.

This patch fixes most of the python3 incompatabilities
within git-clang-format while keeping the script python2 compatible.
There is still one remaining incompatability that prevents using Python3
which is the `str` vs `byte` type change. I plan to put those fixes
up for review separately.

This patch contains fixes for the following incompatabilities:

1) Use the new style Python3 `print` function. This requires importing
   __future__.print_function.

2) Fix incompatability between the Python3 octal prefix and the
   octal prefix Git uses.

3) Replace use of dict.iteritems() with dict.viewitems() because iteritems()
   has been removed in Python3. viewitems() reviews python 2.7 but that is
   also what the script is documented as requiring.
