r247346 - [MS ABI] Make member pointers return true for isIncompleteType

[Hans Wennborg via cfe-commits]

This made the Chromium build sad. For example:
http://build.chromium.org/p/chromium.fyi/builders/ClangToTWin/builds/3092/steps/compile/logs/stdio

Reduction:

$ clang -cc1 -triple i686-pc-windows-msvc18.0.0 -w -fms-extensions
-fms-compatibility -fms-compatibility-version=18.0 -std=c++11
-fdelayed-template-parsing a.ii

template <class C, int (C::*M)(int *, const int &, int &, int &)>
void JSMethod(char *, char *, int);
class A {
  int printd(int *, const int &, int &, int &);
  int printd_info;
  void printd() { JSMethod<A, &A::printd>("", "", printd_info); }
};
