Update constexpr implementation to match CWG's chosen approach for core issues 1358, 1360, 1452 and 1453. - Instantiations of constexpr functions are always constexpr. This removes the need for separate declaration/definition checking, which is now gone. - This makes it possible for a constexpr function to be virtual, if they are only dependently virtual. Virtual calls to such functions are not constant expressions. - Likewise, it's now possible for a literal type to have virtual base classes. A constexpr constructor for such a type cannot actually produce a constant expression, though, so add a special-case diagnostic for a constructor call to such a type rather than trying to evaluate it. - Classes with trivial default constructors (for which value initialization can produce a fully-initialized value) are considered literal types. - Classes with volatile members are not literal types. - constexpr constructors can be members of non-literal types. We do not yet use static initialization for global objects constructed in this way. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@150359 91177308-0d34-0410-b5e6-96231b3b80d8

Update all tests other than Driver/std.cpp to use -std=c++11 rather than -std=c++0x. Patch by Ahmed Charles! git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@141900 91177308-0d34-0410-b5e6-96231b3b80d8

constexpr: semantic checking for constexpr functions and constructors. Based in part on patches by Peter Collingbourne. We diverge from the C++11 standard in a few areas, mostly related to checking constexpr function declarations, and not just definitions. See WG21 paper N3308=11-0078 for details. Function invocation substitution is not available in this patch; constexpr functions cannot yet be used from within constant expressions. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@140926 91177308-0d34-0410-b5e6-96231b3b80d8
