Haojian Wu 678f65a9b4 [clang-tidy] Make 'modernize-use-nullptr' check work on multiple nested implicit cast expressions.
Summary:
For some test cases like:

```
 int func(int, void*, void*);
(double)func(0, 0, 0);
```

The AST contains several `ImplicitCastExpr`s, so we should not only check on the first sub expression.

```
 `-CStyleCastExpr 0x7fe43a088938 <line:6:3, col:24> 'double' <NoOp>
      `-ImplicitCastExpr 0x7fe43a088920 <col:11, col:24> 'double' <IntegralToFloating>

            `-IntegerLiteral 0x7fe43a088840 <col:23> 'int' 0

Benjamin Kramer 8f5eb56df3 [clang-tidy] Add "clang-tidy as a clang plugin" skeleton.
This doesn't really do much at the moment. You can load it via libclang
and set the -checks via an extra command line argument as illustrated in
the test case. Support for other options (including headers check) is
currently missing. Also when using this with libclang some checks may
not work with the precompiled preamble in place.

This can be used to easily show clang-tidy warnings in an editor
integration as all that's needed is adding command line flags that are
passed into libclang. Warnings and FixIts are exposed via the existing
CXDiagnostic machinery.

Felix Berger ffae543b39 [clang-tidy] ClangTidy check to flag uninitialized builtin and pointer fields.
Summary:
This patch is a continuation of http://reviews.llvm.org/D10553 by Jonathan B Coe.

The main additions are:

1. For C++11 the check suggests in-class field initialization as fix. This
makes the fields future proof towards the addition of new constructors.
2 For older language versions the fields are added in the right position
in the initializer list with more tests.
3. User documentation.
