We match on the generated FunctionDecl of the lambda and try to fix it.
This causes a crash.
The right behavior is to ignore lambdas, because they are a definition.

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:
Use a recursive visitor instead of forEachDescendant() matcher.
The latter requires several layers of virtual function calls for each node and
it is more expensive than the visitor.
Benchmark results show improvement of ~6% walltime in clang-tidy.

Summary:
The string class contains methods which support receiving either a string literal or a string object.
For example, calls to append can receive either a char* or a string.
```
string& append (const string& str);
string& append (const char* s);
```
Which make these cases equivalent, and the .c_str() useless:
```
std::string s = "123";
str.append(s);
str.append(s.c_str());
```
In these cases, removing .c_str() doesn't provide any size or speed improvement.
It's only a readability issue.
If the string contains embedded NUL characters, the string literal and the string
object won't produce the same semantic.

Going through a string removes some of the smarts of the diagnosic printer
and makes the code more complicated. This change has some cosmetic impact
on the output but that's mostly minor.

Differential Revision: http://reviews.llvm.org/D18408
llvm-svn: 264856
Summary:
The current checker is able to recognize std::string but does not recognize other string variants.
This patch is adding the support for any string defined with basic_string without considering the
the underlying char type.
The most common variant is: 'std::wstring' based on 'wchar_t'.
There are also other string variants added to the standard: u16string, u32string, etc...

Summary:
The string constructors are not defined using optional parameters and are not recognize by the checker.
The constructor defined in the MSVC header is defined with 1 parameter. Therefore, patterns are not recognized by the checker.
The current patch add support to accept constructor with only one parameter.
Repro on a Visual Studio 14 installation with the following code:
```
void f1(const std::string &s) {
f1(s.c_str());
}
```
In the xstring.h header, the constructors are defined this way:
```
basic_string(const _Myt& _Right) [...]
basic_string(const _Myt& _Right, const _Alloc& _Al) [...]
```
The CXXConstructExpr to recognize only contains 1 parameter.
```
CXXConstructExpr 0x3f1a070 <C:\src\llvm\examples\test.cc:6:6, col:14> 'const std::string':'const class std::basic_string<char, struct std::char_traits<char>, class

Summary:
The string constructors are not defined using optional parameters and are not recognized by the redundant-string-init checker.
The following patch fixes the redundant-string-init checker for the Visual Studio 14 headers file.
The matcher now accept both variant (with 1 and 2 parameters).
Also added new unittests.
