Summary:
Previously, we tried to cover all "std::initializer_list" implicit conversion
cases in the code, but there are some corner cases that not covered (see
newly-added test in the patch).

Sipping all implicit AST nodes is a better way to filter out all these cases.

The check still generates fixes for std::vector (`auto p =

vector behavior in test align with std::vector (both AST nodes are the same now).

Custom make_ calls can be removed for custom tuple-like types -- two new options that control that are `TupleTypes` and `TupleMakeFunctions`. By default, the check removes calls to `std::make_pair` and `std::make_tuple`.

Eq.

```

Summary:
This patch fixes [[ https://bugs.llvm.org/show_bug.cgi?id=32896 | PR32896 ]].

The problem was that modernize-use-emplace incorrectly removed changed push_back into emplace_back, removing explicit constructor call with initializer list parameter, resulting in compiler error after applying fixits.
modernize-use-emplace used to check if matched constructor had InitListExpr, but didn't check against CXXStdInitializerListExpr.

Haojian Wu b780c59b93 [clang-tidy] Fix a false positive on modernize-use-nullptr check.
Summary:
The false positive happens on two neighbour CXXDefaultArgExpr AST nodes.
like below:

```
CXXFunctionalCastExpr 0x85c9670 <col:7, col:23> 'struct ZZ' functional cast to struct ZZ <ConstructorConversion>
 `-CXXConstructExpr 0x85c9518 <col:7, col:23> 'struct ZZ' 'void (uint64, const uint64 *)'
   |-CallExpr 0x85a0a90 <col:10, col:22> 'uint64':'unsigned long long'
   | |-ImplicitCastExpr 0x85a0a78 <col:10> 'uint64 (*)(uint64)' <FunctionToPointerDecay>
   | | `-DeclRefExpr 0x85a09f0 <col:10> 'uint64 (uint64)' lvalue Function 0x85a06a0 'Hash' 'uint64 (uint64)'
   | `-CXXDefaultArgExpr 0x85a0ac8 <<invalid sloc>> 'uint64':'unsigned long long'
   `-CXXDefaultArgExpr 0x85c94f8 <<invalid sloc>> 'const uint64 *'
```

For each particular CXXDefaultArgExpr node, we need to reset
FirstSubExpr, otherwise FirstSubExpr will refer to an incorrect expr.

Haojian Wu 157e46dd45 [Clang-tidy]: Fix modernize-avoid-bind erroneous scope resolution.
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.

Kirill Bobyrev 8694cb97c2 [clang-tidy] minor improvements in modernise-deprecated-headers check
This patch introduces a minor list of changes as proposed by Richard Smith in
the mailing list.

See original comments with an impact on the future check state below:

[comments.begin

> +                          {"complex.h", "ccomplex"},

It'd be better to convert this one to <complex>, or leave it alone.
<ccomplex> is an unnecessary wart.

(The contents of C++11's <complex.h> / <ccomplex> / <complex> (all of
which are identical) aren't comparable to C99's <complex.h>, so if
this was C++98 code using the C99 header, the code will be broken with
or without this transformation.)

> +                          {"iso646.h", "ciso646"},

Just delete #includes of this one. <ciso646> does nothing.

> +              {"stdalign.h", "cstdalign"},
> +              {"stdbool.h", "cstdbool"},

We should just delete these two includes. These headers do nothing in C++.
