Finds memset() calls with potential mistakes in their arguments.

Maybe for special cases, there could be later additions to this basic checker.
This is the first checker I wrote and I never did something with clang (only compiling programs). So whenever I missed conventions or did plain retarded stuff, feel free to point it out! I am willing to fix them and write a better checker.

General overhaul to fix many coding bugs, simplify the code, and improve readability.
* Clarify documentation strings of user options.
* Say that clang-include-fixer-executable is a file to have auto completion.
* Allow user to select available options for clang-include-fixer-input-format. Turn it into a symbol as it's not a free-form string.
* Remove clang-include-fixer-query-mode. This option was apparently used to select between two different operation modes, which is not a typical use case for user options. Provide two separate commands instead.
* Add a face for the overlay highlighting so that users can customize it.
Move user commands to the front so that readers of the code aren't buried in internal functions.
* Make process calls asynchronous. This is possible here because clang-include-fixer doesn't change files in place. This means input is no longer blocked while clang-include-fixer is running.
* Factor out logic in helper functions to keep functions short.
* Add comments where appropriate.
* Provide an alternative buffer replacement strategy for the case that a single line was inserted (the normal case in the case of clang-include-fixer). This keeps point, markers, and other buffer information intact.
* Use let-alist and association lists instead of property lists to shorten the code.
* Instead of highlighting only the first occurrence of a symbol, highlight all occurrences and move point to the closest one.
* Detect qualified names at point.
* Use filepos-to-bufferpos if available.
* Formatting.

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.

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().
This patch requires D23004 to be submitted before it.

Change Vim key binding for include-fixer (`,cf` -> `<leader>cf`) and
clang-rename (`,cr` -> `<leader>cr`) to use `<leader>` instead of `,` like
cool Vim people (tm) do.

Summary:
This check verifies if buffer type and MPI (Message Passing Interface)
datatype pairs match. All MPI datatypes defined by the MPI standard (3.1)
are verified by this check. User defined typedefs, custom MPI datatypes and
null pointer constants are skipped, in the course of verification.
Instructions on how to apply the check can be found at: https://github.com/0ax1/MPI-Checker/tree/master/examples

clang-rename needs at least to have a minimum documentation to provide a
small introduction for new users

llvm-svn: 275388
Summary:
Make check more useful in the following two cases:
The parameter is passed by non-const value, has a non-deleted move constructor and is only referenced once in the function as argument to the type's copy constructor.
The parameter is passed by non-const value, has a non-deleted move assignment operator and is only referenced once in the function as argument of the the type's copy assignment operator.
In this case suggest a fix to move the parameter which avoids the unnecessary copy and is closest to what the user might have intended.

Summary:
Added support for macro definitions.
--
1. Added a pre-processor callback to catch macro definitions
2. Changed the type of the failure map so that macros and declarations can share the same map
3. Added extra tests to ensure fix-ups work using the new map
4. Added fix-ups for type aliases in variable and function declarations as part of adding the new tests

Summary:
Conceptually, this is very close to the existing functionality of misc-move-const-arg, which is why I'm adding it here and not creating a new check. For example, for a type A that is both movable and copyable, this
const A a1;
A a2(std::move(a1));
is not only a case where a const argument is being passed to std::move(), but the result of std::move() is also being passed as a const reference (due to overload resolution).
The new check typically triggers (exclusively) in cases where people think they're dealing with a movable type, but in fact the type is not movable.

Differential Revision: http://reviews.llvm.org/D21223
llvm-svn: 272896
Summary:
By default, modernize-use-auto check will retain stars when replacing an explicit type with `auto`: `MyType *t = new MyType;` will be changed to `auto *t = new MyType;`, thus resulting in more consistency with the recommendations to use `auto *` for iterating over pointers in range-based for loops: http://llvm.org/docs/CodingStandards.html#beware-unnecessary-copies-with-auto
The new `RemoveStars` option allows to revert to the old behavior: with the new option turned on the check will change `MyType *t = new MyType;` to `auto t = new MyType;`.
