Similarly to the code we already had for builtin functions, we need to
check the call expression for the arguments passed.

ff80fc0ea2 [clang][Interp] Implement __builtin_isnan()
The previous version was using llvm::reverse(CallExpr::arguments()),
which causes problems when clang is compiled with GCC.

eaadbcd5e0 [clang][Interp] Implement __builtin_strcmp
Make our Function class keep a list of parameter offsets so we can
simply get a parameter by index when evaluating builtin functions.

e8fb478f2d [clang][Interp] Don't call getSource() on functions without a body
For builtin functions, we create a Function instance without a body or
code. When emitting diagnostics from them, we need a proper SourceInfo
to point to, but the only thing we can use is the call site of the
builtin function.

cc79ddb52c [clang][Interp] Check instance pointers before calling functions on them
Remove the double Call() implementation to reduce code duplication. Then
fix Function::getSource() so we can diagnose instance pointers being
null.

0ddd13acc9 [clang][Interp] Implement This pointer passing to methods
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.

950b70dcc7 [Clang Interpreter] Initial patch for the constexpr interpreter
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.

2c9f83cfab Revert "[Clang Interpreter] Initial patch for the constexpr interpreter"
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.
