Summary:
Previously, all #includes (includeing old_header.h) in old.cc will be copied to new.cc,
however, the new.cc should include new_header.h instead of the old_header.h
Before applying the patch, the new.cc looks like:
```
#include "old_header.h"
...
```
The new.cc looks like with this patch:
```
#include "new_header"
...
```

Summary:
This patch introduces a new tool which moves a specific class definition
from files (.h, .cc) to new files (.h, .cc), which mostly acts like
"Extract class defintion". In the long term, this tool should be
merged in to clang-refactoring as a subtool.
clang-move not only moves class definition, but also moves all the
forward declarations, functions defined in anonymous namespace and #include
headers to new files, to make sure the new files are compliable as much
as possible.
To move `Foo` from old.[h/cc] to new.[h/cc], use:
```
clang-move -name=Foo -old_header=old.h -old_cc=old.cc -new_header=new.h
-new_cc=new.cc old.cc
```
To move `Foo` from old.h to new.h, use:
```
clang-move -name=Foo -old_header=old.h -new_header=new.h old.cc
```

Summary:
A tool for changing surrouding namespaces of class/function definitions while keeping
references to types in the changed namespace correctly qualified by prepending
namespace specifiers before them.
Example: test.cc
namespace na {
class X {};
namespace nb {
class Y { X x; };
} // namespace nb
} // namespace na
To move the definition of class Y from namespace "na::nb" to "x::y", run:
clang-change-namespace --old_namespace "na::nb" \
--new_namespace "x::y" --file_pattern "test.cc" test.cc --
Output:
namespace na {
class X {};
} // namespace na
namespace x {
namespace y {
class Y { na::X x; };
} // namespace y
} // namespace x

Having both rename-at and rename-all both seems confusing and introduces
unneeded difficulties. After merging rename-at and rename-all maintaining main
function wrappers and custom help becomes redundant while CLI becomes less
confusing.
D24224 (which was the original patch causing buildbot failures) wasn't aware of
bugs caused by passing both -offset and -qualified-name. After D24224 was landed
it caused buildbot failures and therefor I just reverted it.
Two things that make this patch different from D24224 are:
* unittests/clang-rename was deleted, because it is unmaintained and doesn't do
much.
* Passing both `-offset` and `-qualified-name` isn't allowed anymore for the
sake of preventing bugs.
This patch is a trivial enhancement of accepted D24224 revision.

prefer to omit braces around flow control statements with single line body.
For example the following piece of code

is preferred to
```

Summary:
The check emits a warning if std::move() is applied to a forwarding reference, i.e. an rvalue reference of a function template argument type.
If a developer is unaware of the special rules for template argument deduction on forwarding references, it will seem reasonable to apply std::move() to the forwarding reference, in the same way that this would be done for a "normal" rvalue reference.
This has a consequence that is usually unwanted and possibly surprising: If the function that takes the forwarding reference as its parameter is called with an lvalue, that lvalue will be moved from (and hence placed into an indeterminate state) even though no std::move() was applied to the lvalue at the callsite.
As a fix, the check will suggest replacing the std::move() with a std::forward().

As Alexander pointed out, LLVM Coding Standards are more conservative about

* When the type is obvious, i.e. explicitly mentioned in the same expression.
For example `if (const clang::FieldDecl *FieldDecl = Initializer->getMember())`.
* When the type is totally non-obvious and one iterates over something. For
example
`for (const auto &CurrDecl : Context.getTranslationUnitDecl()->decls())`.
Otherwise the type should be explicitly stated.

The include order check would get notified of all include
directives in a depth-first manner. This created the
possibility of an include directive from a header file
interfering with the sort order of a set of two distinct

With this patch we bucket the include directives by the file

so that directives from different files do not get mixed

This differs from the previous version by being more careful about template
instantiation/specialization in order to prevent errors when building with
clang -Werror. Specifically:
* begin is not defined in the template and is instead instantiated when Head
is. I think the warning when we don't do that is wrong (PR28815) but for now
at least do it this way to avoid the warning.
* Instead of performing template specializations in LLVM_INSTANTIATE_REGISTRY
instead provide a template definition then do explicit instantiation. No
compiler I've tried has problems with doing it the other way, but strictly
speaking it's not permitted by the C++ standard so better safe than sorry.
Original commit message:
Currently the Registry class contains the vestiges of a previous attempt to
allow plugins to be used on Windows without using BUILD_SHARED_LIBS, where a
plugin would have its own copy of a registry and export it to be imported by
the tool that's loading the plugin. This only works if the plugin is entirely
self-contained with the only interface between the plugin and tool being the
registry, and in particular this conflicts with how IR pass plugins work.
This patch changes things so that instead the add_node function of the registry
is exported by the tool and then imported by the plugin, which solves this
problem and also means that instead of every plugin having to export every
registry they use instead LLVM only has to export the add_node functions. This
allows plugins that use a registry to work on Windows if
LLVM_EXPORT_SYMBOLS_FOR_PLUGINS is used.

include-fixer will firstly try to use scoped namespace context information to

search, because it might treat the identifier as a nested class of scoped
namespace.
Given the following code, and the symbol database only has two classes: "foo" and
"b::Bar".
namespace foo { Bar t; }
Before getting fixing, include-fixer will never search "Bar" symbol.
Because it firstly tries to search "foo::Bar", there is no "Bar" in foo namespace,
then it finds "foo" in database finally. So it treats "Bar" is a nested class
of "foo".

The complexity of renaming a USR is O(N) [N stands for number of nodes in
Translation Unit]. In some cases there are more than one USR for a single symbol
(see overridden functions and ctor/dtor handling), which means that the
complexity of finding all of the corresponding USRs is O(N * M) [M stands for
number of USRs corresponding to the symbols, which may be not quite small]. With
a simple tweak we can make it O(N * log(M)) by passing whole list of USRs
corresponding to the symbol to USRLocFinder.
