[OpenCL] Add separate read_only and write_only pipe IR types
SPIR-V encodes the read_only and write_only access qualifiers of pipes, so separate LLVM IR types are required to target SPIR-V. Other backends may also find this useful. These new types are `opencl.pipe_ro_t` and `opencl.pipe_wo_t`, which replace `opencl.pipe_t`. This replaces __get_pipe_num_packets(...) and __get_pipe_max_packets(...) which took a read_only pipe with separate versions for read_only and write_only pipes, namely: * __get_pipe_num_packets_ro(...) * __get_pipe_num_packets_wo(...) * __get_pipe_max_packets_ro(...) * __get_pipe_max_packets_wo(...) These separate versions exist to avoid needing a bitcast to one of the two qualified pipe types. Patch by Stuart Brady.
