Before, when emitting a regular integer constant, we went:
Int -> APInt -> int -> emit
Fix this by using regular integer constants in emitConst() and instead
converting APInt to those once.
This reverts commit 6fa1795d1f.
This breaks a windows builder:
../../clang/lib/AST/Interp/ByteCodeExprGen.h(236,11): error: call to constructor of 'clang::interp::APInt' (aka 'llvm::APInt') is ambiguous
APInt WrappedValue(getIntWidth(Ty), Value, std::is_signed<T>::value);

Implement ArrayInitLoopExprs, which are used in copy constructors to
copy arrays. Also fix problems encountered while doing that.

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.

Implement negating and inverting values. Also implement
IntegralToBoolean casts so the operations are easier to test.

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.
