clang accepts both #include and #import for includes (the latter having an
implicit header guard). Let clang-format interleave both types if
--sort-includes is passed. #import is used frequently in Objective-C code.

The MemoizationData cache was introduced to avoid a series of enum
compares at the cost of making DynTypedNode bigger. This change reverts
to using an enum compare but instead of building a chain of comparison
the enum values are reordered so the check can be performed with a
simple greater than. The alternative would be to steal a bit from the
enum but I think that's a more complex solution and not really needed
here.
I tried this on several large .cpp files with clang-tidy and didn't
notice any performance difference. The test change is due to matchers
being sorted by their node kind.

Putting DynTypedNode in the ParentMap bloats its memory foot print.
Before the void* key had 8 bytes, now we're at 40 bytes per key which
can mean multiple gigabytes increase for large ASTs and this count
doesn't even include all the added TypeLoc nodes. Revert until I come
up with a better data structure.
This reverts commit r250831.

The logic for parsing FP capabilities to set __ARM_FP was mistakenly removing
the Half-Precision capability when handling fp-only-sp resulting in a value
of 0x4. Section 6.5.1 of ACLE states that for such FP architectures the value
should be 0x6

headers. If those headers end up being textually included twice into the same
module, we get ambiguity errors.
Work around this by downgrading the ambiguity error to a warning if multiple
identical internal-linkage functions appear in an overload set, and just pick
one of those functions as the lookup result.

This time, I went with the first approach from
http://reviews.llvm.org/D6700, where clang actually attempts to form an
implicit member reference from an UnresolvedLookupExpr. We know that
there are only two possible outcomes at this point, a DeclRefExpr of the
FieldDecl or an error, but its safer to reuse the existing machinery for
this.

Microsoft's ATL headers make use of this MSVC extension, add support for
it and issue a diagnostic under -Wmicrosoft-exception-spec.
This fixes PR25265.

Clang will now accept this valid C++11 code:
struct A { int field; };
struct B : A {
using A::field;
enum { TheSize = sizeof(field) };
};
Previously we would classify the 'field' reference as something other
than a field, and then forget to apply the C++11 rule to allow
non-static data member references in unevaluated contexts.
This usually arises in class templates that want to reference fields of
a dependent base in an unevaluated context outside of an instance
method. Such contexts do not allow references to 'this', so the only way
to access the field is with a using decl and an implicit member
reference.

This change makes LLVM_BUILD_EXTERNAL_COMPILER_RT work correctly when overriding CMAKE_INSTALL_PREFIX on the install action (which is how LLVM_CREATE_XCODE_TOOLCHAIN works).
This fix is two parts:
(1) Pass CMAKE_INSTALL_PREFIX in as a variable from the parent install to the child install
(2) When passing COMPILER_RT_INSTALL_PATH into the external project make sure it is passed as a string not a path.
Not specifying the full path for COMPILER_RT_INSTALL_PATH isn't enough to fix the issue because relative paths specified on the CMake command line are expanded relative to the working directory before the cache is populated. Forcing this to a string allows it to remain a relative path through to the install() calls. Relative paths specified in install() calls are expanded relative to CMAKE_INSTALL_PREFIX at install time.

Firstly this changes the type of parent map to be keyed on DynTypedNode to
simplify the following changes. This comes with a DenseMapInfo for
DynTypedNode, which is a bit incomplete still and will probably only work
for parentmap right now.
Then the RecursiveASTVisitor in ASTContext is updated and finally
ASTMatchers hasParent and hasAncestor learn about the new functionality.
Now ParentMap is only missing TemplateArgumentLocs and CXXCtorInitializers.

According to the Intel documentation, the mask operand of a maskload and
maskstore intrinsics is always a vector of packed integer/long integer values.
This patch introduces the following two changes:
1. It fixes the avx maskload/store intrinsic definitions in avxintrin.h.
2. It changes BuiltinsX86.def to match the correct gcc definitions for avx
maskload/store (see D13861 for more details).

This reverts commit r250592.
It has issues around unevaluated contexts, like this:
template <class T> struct A { T i; };
template <class T>
struct B : A<T> {
using A<T>::i;
typedef decltype(i) U;
};
template struct B<int>;

Out-of-line definitions of static data members which have an inline
initializer must get GVA_DiscardableODR linkage instead of
GVA_StrongExternal linkage.
MSVC 2013's behavior is different with respect to this and would cause
link errors if one TU provided a definition while another did not.
MSVC 2015 fixed this bug, making this OK. Note that the 2015 behavior
is always compatible with 2013: it never produces a strong definition.
This essentially reverts r237787.

This makes the format tests look more like most other FileCheck tests in clang.
The multiple-inputs tests still use temp files, to make sure that the file
input code in clang-format stays tested.
Stop stripping out the comment lines in style-on-command-line.cpp as they don't
get in the way and it makes the test simpler. Also remove 2>&1s on the tests in
that file that don't need it.

-assume-filename, -fallback-style, and -sort-includes are new. (They're also
longer than the previous options, so all descriptions shift over by some amount,

If no arguments are specified, it formats the code from standard input
and writes the result to the standard output.
If <file>s are given, it reformats the files. If -i is specified
together with <file>s, the files are edited in-place. Otherwise, the
result is written to the standard output.
USAGE: clang-format [options] [<file> ...]
OPTIONS:
-assume-filename=<string> - When reading from stdin, clang-format assumes this
filename to look for a style config file (with
-style=file) and to determine the language.
-cursor=<uint> - The position of the cursor when invoking
clang-format from an editor integration
-dump-config - Dump configuration options to stdout and exit.
Can be used with -style option.
-fallback-style=<string> - The name of the predefined style used as a
fallback in case clang-format is invoked with
-style=file, but can not find the .clang-format
file to use.
Use -fallback-style=none to skip formatting.
-help - Display available options (-help-hidden for more)
-i - Inplace edit <file>s, if specified.
-length=<uint> - Format a range of this length (in bytes).
Multiple ranges can be formatted by specifying
several -offset and -length pairs.
When only a single -offset is specified without
-length, clang-format will format up to the end
of the file.
Can only be used with one input file.
-lines=<string> - <start line>:<end line> - format a range of
lines (both 1-based).
Multiple ranges can be formatted by specifying
several -lines arguments.
Can't be used with -offset and -length.
Can only be used with one input file.
-offset=<uint> - Format a range starting at this byte offset.
Multiple ranges can be formatted by specifying
several -offset and -length pairs.
Can only be used with one input file.
-output-replacements-xml - Output replacements as XML.
-sort-includes - Sort touched include lines
-style=<string> - Coding style, currently supports:
LLVM, Google, Chromium, Mozilla, WebKit.
Use -style=file to load style configuration from
.clang-format file located in one of the parent
directories of the source file (or current
directory for stdin).
Use -style="{key: value, ...}" to set specific
parameters, e.g.:
-style="{BasedOnStyle: llvm, IndentWidth: 8}"
-version - Display the version of this program output.
