Summary:
Prior to this patch, OpenCL code such as the following would attempt to create
a BranchInst with a non-bool argument:
if (enqueue_kernel(get_default_queue(), 0, nd, ^(void){})) /* ... */
This patch is a follow up on a similar issue with pipe builtin
operations. See commit r280800 and https://bugs.llvm.org/show_bug.cgi?id=30219.
This change, while being conservative on non-builtin functions,
should set the type of expressions invoking builtins to the
proper type, instead of defaulting to `bool` and requiring
manual overrides in Sema::CheckBuiltinFunctionCall.
In addition to tests for enqueue_kernel, the tests are extended to
check other OpenCL builtins.

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.

Fix arc patch fuzz error.
Summary:
Support for the pipe built-in functions for OpenCL 2.0.
The pipe builtin functions may have infinite kinds of element types, one approach
would be to just generate calls that would always use generic types such as void*.
This patch is based on bader's opencl support patch on SPIR-V branch.
