Alexander Kornienko 160d9472f4 Fix -Wshadow false positives with function-local classes. 
Summary:
Fixes http://llvm.org/PR33947.

https://godbolt.org/g/54XRMT

void f(int a) {
  struct A {
    void g(int a) {}
    A() { int a; }
  };
}

3 : <source>:3:16: warning: declaration shadows a local variable [-Wshadow]
    void g(int a) {}
               ^
1 : <source>:1:12: note: previous declaration is here
void f(int a) {

void f(int a) {
           ^
2 warnings generated.

The local variable `a` of the function `f` can't be accessed from a method of
the function-local class A, thus no shadowing occurs and no diagnostic is
needed.
