Summary:
Warn about special member functions that only contain a comment.
Report the location of the special member function, unless it is
defined in a macro.  Reporting the location of the body in a macro is
more helpful as it causes the macro expansion location to be reported too.

Fixes PR30920.

llvm-svn: 287215

Summary:
This patch adds handling for member initializers in a constructors initializer list. Previously we only handled base-class and delegating initializers, which are transformed by the `TypeLoc` matcher. For Example:

```
// Style options: All identifiers should start with an upper case letter.
struct base { ...  }; 
struct der :  base {
  int field;  // FIXES: int Field;
  der() : der(42) {} // FIXES: Der() : Der(42) {}
  der(int X) : base(), field(X) {} // FIXES: Der(int X) : Base(), field(X)
  // Note that `field` doesn't get replaced
};
```

[change-namespace] handle constructor initializer: Derived : Base::Base() {} and added conflict detections

Summary:
namespace nx { namespace ny { class Base { public: Base(i) {}} } }
namespace na {
namespace nb {
class X : public nx::ny {
public:
  X() : Base::Base(1) {}
};
}
}

When changing from na::nb to x::y, "Base::Base" will be changed to "nx::ny::Base" and
 "Base::" in "Base::Base" will be replaced with "nx::ny::Base" too, which causes
conflict. This conflict should've been detected when adding replacements but was hidden by `addOrMergeReplacement`. We now also detect conflict when adding replacements where conflict must not happen.

The namespace lookup is tricky here, we simply replace "Base::Base()" with "nx::ny::Base()" as a workaround, which compiles but not perfect.

Summary:
clang-tidy should fix identifier naming even when the identifier is
referenced inside a macro expansion, provided that the identifier enters
the macro expansion completely within a macro argument.

For example, this will allow fixes to the naming of the identifier
'global' when it is declared and used as follows:

  int global;
  #define USE_IN_MACRO(m) auto use_##m = m
  USE_IN_MACRO(global);

Hello, i would like to suggest a fix for one of the checks in clang-tidy and i should hope this one is the correct mailing list.
The check is modernize-avoid-bind.

Consider the following:

  void bar(int x, int y);

  namespace N {
    void bar(int x, int y);
  }

  void foo(){
    auto Test = std::bind(N::bar,1,1);
  }

clang-tidy’s modernize-avoid-bind check suggests writing:

  void foo(){
    auto Test =[] {return bar(1,1);};
  }

instead of:

  void foo(){
    auto Test = [] {return N::bar(1,1);};
  }

So clang-tidy has proposed an incorrect Fix.
