[PATCH] D46015: [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(...)
