The `print` function has been available as a __future__ import since

Switch clang-format over to Rewriter::overwriteChangedFiles().

The previous implementation was attempting to stream back directly to the
original file and failing if it was already memory mapped by MemoryBuffer,
an operation unsupported by Windows.

MemoryBuffer generally mmaps files larger than the physical page size so
this will have been difficult to reproduce consistently.

This change also reduces flicker in code editors and IDEs on all platforms
when reformatting in-place.

Note that other incorrect uses of MemoryBuffer exist in LLVM/clang and
will need a similar fix.

A test should be added for Windows when libFormat performance issues are
fixed (it takes longer than a day to format a 1MB file at present!)

results in both codepaths being a lot cleaner and simpler, and fixes some bugs
where the type argument handling bled into the expression argument handling and
caused us to both accept invalid and reject valid attribute arguments.

Some of the shared compiler/linker flags start with -m, so they've been
getting passed to the compiler only since r180073. Now, the -m* wildcard
is processed after the shared flags and the ignored flags.

Changed clang-format-diff.py to output diff by default. Added -i option to apply changes to files instead.

Summary:
"svn diff|clang-format-diff.py" will just output the diff.
Now it's possible to use:
  svn diff|clang-format-diff.py|patch -p0
as an equivalent to:
  svn diff|clang-format-diff.py -i
;)

Patch by Alp Toker. Many thanks!

Original descriptions:
clang-format-diff incorrectly modifies unchanged lines due to an error
in diff parsing.

The unified diff format has a default line change count of 1, and 0 may
be specified to indicate that no lines have been added. This patch
updates the parser to accurately reflect the diff specification.

This also has the benefit of stabilising the operation so it will
produce the same output when run multiple times on the same changeset,
which was previously not the case.

No tests added because this script is not currently tested (though we
should look into that!)

The previous change caused the driver to translate -Wa,-L to the

LLVM supports applying conversion instructions to vectors of the same number of
elements (fptrunc, fptosi, etc.) but there had been no way for a Clang user to
cause such instructions to be generated when using builtin vector types.

C-style casting on vectors is already defined in terms of bitcasts, and so
cannot be used for these conversions as well (without leading to a very
confusing set of semantics). As a result, this adds a __builtin_convertvector
intrinsic (patterned after the OpenCL __builtin_astype intrinsic). This is
intended to aid the creation of vector intrinsic headers that create generic IR
instead of target-dependent intrinsics (in other words, this is a generic
_mm_cvtepi32_ps). As noted in the documentation, the action of
__builtin_convertvector is defined in terms of the action of a C-style cast on
each vector element.

This is necessary when running two scan-build processes in parallel. The
directory naming scheme is now:

  yyyy-MM-dd-HHmmss-PID-N
  2013-09-13-174210-123-1

where "PID" is the scan-build process ID, and "N" is a sequential counter
(not likely to be needed now that seconds are mangled in, but just in case).

Let me tell you a tale...

Within some twisted maze of debug info I've ended up implementing an
insane man's Include What You Use device. When the debugger emits debug
info it really shouldn't, I find out why & then realize the code could
be improved too.

In this instance CIndexDiagnostics.cpp had a lot more debug info with
Clang than GCC. Upon inspection a major culprit was all the debug info
describing clang::Sema. This was emitted because clang::Sema is
befriended by DiagnosticEngine which was rightly required, but GCC
doesn't emit debug info for friends so it never emitted anything for
Clang. Clang does emit debug info for friends (will be fixed/changed to
reduce debug info size).

But why didn't Clang just emit a declaration of Sema if this entire TU
didn't require a definition?

1) Diagnostic.h did the right thing, only using a declaration of Sema
and not including Sema.h at all.
2) Some other dependency of CIndexDiagnostics.cpp didn't do the right
thing. ASTUnit.h, only needing a declaration, still included Sema.h
(hence this commit which removes that include and adds the necessary
includes to the cpp files that were relying on this)
3) -flimit-debug-info didn't save us because of
EnterExpressionEvaluationContext, defined inline in Sema.h which fires
the "requiresCompleteType" check/flag (since it uses nested types from
Sema and calls Sema member functions) and thus, if debug info is ever
emitted for the type, the whole type is emitted and not just a
declaration.

Improving -flimit-debug-info to account for this would be... hard.
Modifying the code so that's not 'required to be complete' might be
possible, but probably only by moving EnterExpressionEvaluationContext
either into Sema, or out of Sema.h. That might be a bit too much of a
contortion to be bothered with.

Also, this is only one of the cases where emitting debug info for
friends caused us to emit a lot more debug info (this change reduces
Clang's DWO size by 0.93%, dropping friends entirely reduces debug info
by 3.2%) - I haven't hunted down the other cases, but I assume they
might be similar (Sema or something like it). IWYU or a similar tool
might help us reduce build times a bit, but analyzing debug info to find
these differences isn't worthwhile. I'll take the 3.2% win, provide this
small improvement to the code itself, and move on.

With -style=file, clang-format now starts to search for a .clang-format
file starting at the file given with -assume-filename if it reads from
stdin. Otherwise, it would start searching from the current directory,
which is not helpful for editor integrations.

Also changed vim, emacs and sublime integrations to actually make use of
this flag.

Dotfiles are impractical on Windows. This makes clang-format search
for the style configuration file as '_clang-format' in addition to
the usual '.clang-format'. This is similar to how VIM searches for
'_vimrc' on Windows.
