Currently, -fdeclare-opencl-builtins always adds the generic address space overloads of e.g. the vload builtin functions in OpenCL 3.0 mode, even when the generic address space feature is disabled. Guard the generic address space overloads by the `__opencl_c_generic_address_space` feature instead of by OpenCL version. Guard the private, global, and local overloads using the internal `__opencl_c_named_address_space_builtins` feature. Differential Revision: https://reviews.llvm.org/D107769
