Constant expression evaluation: support for constexpr member functions. This reinstates r144273; a combination of r144333's fix for NoOp rvalue-to-lvalue casts and some corresponding changes here resolve the regression which that caused. This patch also adds support for some additional forms of member function call, along with additional testing. llvm-svn: 144369 2011-11-11 12:05:33 +08:00			`// RUN: %clang_cc1 -std=c++11 -fsyntax-only %s`
