'pipe' keyword is introduced in OpenCL C 2.0: so do checks for OpenCL C version while
parsing and then later on check for language options to construct actual pipe. This feature
requires support of __opencl_c_generic_address_space, so diagnostics for that is provided as well.

This is the same patch as in D106748 <https://reviews.llvm.org/D106748> but with a tiny fix in checking of diagnostic messages.
Also added tests when program scope global variables are not supported.
