Sven van Haastregt df5a905aa8 [OpenCL] Add ExtVectorElementExpr constant evaluation (PR42387) 
Add constexpr evaluation for ExtVectorElementExpr nodes by evaluating
the underlying vector expression.  Add basic folding for the case that
Evaluate does not return an LValue.

Sven van Haastregt f3e6a61232 [OpenCL] Handle address space conversions for constexpr (PR44177) 
The AST for the constexpr.cl test contains address space conversion
nodes to cast through the implicit generic address space.  These
caused the evaluator to reject the input as constexpr in C++ for
OpenCL mode, whereas the input was considered constexpr in plain C++
mode as the AST won't have address space cast nodes then.

Fixes PR44177.
