[PATCH] [ms-cxxabi] Add CGCXXABI::NeedsBodylessEmission function.

[Timur Iskhodzhanov]

  LGTM for me with one suggestion,

================
Comment at: lib/CodeGen/CGCXXABI.h:322
@@ +321,3 @@
+  /// Returns true if the ABI requires that we emit a definition for this
+  /// function, given that we don't have a definition for it in the TU.
+  virtual bool NeedsBodylessEmission(GlobalDecl GD);

Would be nice to give an example of when it's needed, otherwise it's a bit cryptic.
