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.

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;`.

Summary:
Also trigger the check in the following case:
void foo() {
ExpensiveToCopy Obj;
const auto UnnecessaryCopy = Obj.constReference();
Obj.onlyUsedAsConst();
}
i.e. when the object the method is called on is not const but is never
modified.

Summary:
We should check whether a UsingDecl is defined in macros or in class
definition, not TargetDecls of the UsingDecl.

Modified the clang-tidy PassByValue check. It now stops adding std::move to type which is trivially copyable because that caused the clang-tidy MoveConstArg to complain and revert, thus creating a cycle.
I have also added a lit-style test to verify the bugfix.

If a use of a macro argument is preceded by the `namespace` keyword, do
not warn that the use should be wrapped in parentheses.

Summary:
This patch is adding support for conditional expression and overloaded operators.
To decrease false-positive, this patch is adding a list of banned macro names that
has multiple variant with same integer value.
Also fixed support for template instantiation and added an unittest.

Summary:
Arguments can be swapped using fixit when they are not in macros.
This is the same implementation than SwappedArguments. Some code
got lifted to be reused.
Others checks are not safe to be fixed as they tend to be bugs or errors.
It is better to let the user manually review them.

Summary:
Fixed a crash in cppcoreguidelines-pro-type-member-init when checking record types with indirect fields pre-C++11.
Fixed handling of indirect fields so they are properly checked and suggested fixes are proposed.
