[libclang] Declaration inside If Statement cursor missing when calling clang_visitChildren

[koyote]

Hi,

The following legal C++17 code produces the following AST if you call clang from the terminal with -Xclang -ast-dump -std=c++17 -fsyntax-only:

void x() {
  if (int i = 0; i < 1)
    return;
}

[...]
FunctionDecl 0x20b5aafe150 <Test.cpp:1:1, line:4:1> line:1:6 x 'void ()'
  `-CompoundStmt 0x20b5aafe3a8 <col:10, line:4:1>
    `-IfStmt 0x20b5aafe388 <line:2:1, line:3:4> has_init
      |-DeclStmt 0x20b5aafe2e0 <line:2:4, col:13>
      | `-VarDecl 0x20b5aafe250 <col:4, col:12> col:8 used i 'int' cinit
      |   `-IntegerLiteral 0x20b5aafe2b8 <col:12> 'int' 0
      |-BinaryOperator 0x20b5aafe358 <col:15, col:19> 'bool' '<'
      | |-ImplicitCastExpr 0x20b5aafe340 <col:15> 'int' <LValueToRValue>
      | | `-DeclRefExpr 0x20b5aafe2f8 <col:15> 'int' lvalue Var 0x20b5aafe250 'i' 'int'
      | `-IntegerLiteral 0x20b5aafe318 <col:19> 'int' 1
      `-ReturnStmt 0x20b5aafe378 <line:3:4>

Note the DeclStmt cursor and children.
However, when using libclang on the same code by calling clang_visitChildren, the DeclStmt cursor and its children are never 'visited'. This was tested using the latest Windows x64 build (9.0.0)
