[OpenCL] Added distinct file extension for C++ for OpenCL. Files compiled with C++ for OpenCL mode can now have a distinct file extension - clcpp, then clang driver picks the compilation mode automatically (-x clcpp) without the use of -cl-std=clc++.

[OpenCL] Enable address spaces for references in 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. Differential Revision: https://reviews.llvm.org/D53764 llvm-svn: 347059

[test] Add {{.*}} to make ELF tests immune to dso_local/dso_preemptable/(none) differences For a default visibility external linkage definition, dso_local is set for ELF -fno-pic/-fpie and COFF and Mach-O. Since default clang -cc1 for ELF is similar to -fpic ("PIC Level" is not set), this nuance causes unneeded binary format differences. To make emitted IR similar, ELF -cc1 -fpic will default to -fno-semantic-interposition, which sets dso_local for default visibility external linkage definitions. To make this flip smooth and enable future (dso_local as definition default), this patch replaces (function) `define ` with `define{{.*}} `, (variable/constant/alias) `= ` with `={{.*}} `, or inserts appropriate `{{.*}} `.

[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. Differential Revision: https://reviews.llvm.org/D71015
