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.

Rename lang mode flag to -cl-std=clc++/-cl-std=CLC++
or -std=clc++/-std=CLC++.
This aligns with OpenCL C conversion and removes ambiguity
with OpenCL C++.

Added references to the addr spaces deduction and enabled
CL2.0 features (program scope variables and storage class
qualifiers) to work in C++ mode too.
Fixed several address space conversion issues in CodeGen
for references.
