The calling convention is:
[RVO pointer]
[instance pointer]
[... args ...]
We handle the instance pointer ourselves, BUT for the RVO pointer, we
just assumed in visitReturnStmt() that it is on top of the stack. Which
isn't true if there are other args present (and a this pointer, maybe).
Fix this by recording the RVO pointer explicitly when creating an
InterpFrame, just like we do with the instance/This pointer.
There is already a "RVOAndParams()" test in test/AST/Inter/records.cpp,
that was supposed to test this, however, it didn't trigger any
problematic behavior because the parameter and the return value have the
same type.

Implement passing the this pointer to member functions and constructors.
The this pointer is passed via the stack. This changes the functions to
explicitly track whether they have a RVO pointer and a this pointer.

Add Call() and CallVoid() ops and use them to call functions. Only
FunctionDecls are supported for now.

This patch adds override to several overriding virtual functions that were missing the keyword within the clang/ directory. These were found by the new -Wsuggest-override.
Summary:
This patch introduces the skeleton of the constexpr interpreter,
capable of evaluating a simple constexpr functions consisting of
if statements. The interpreter is described in more detail in the
RFC. Further patches will add more features.

Breaks BUILD_SHARED_LIBS build, introduces cycles in library dependency
graphs. (clangInterp depends on clangAST which depends on clangInterp)
This reverts r370839, which is an yet another recommit of D64146.
