LOG: [OpenCL] Restore addrspacecast for pipe builtins (#112514)
Commit 84ee629bc515 ("clang: Remove some pointer bitcasts (#112324)",
2024-10-15) triggered some "Call parameter type does not match function
signature!" errors when using the OpenCL pipe builtin functions under
the spir triple, due to a missing addrspacecast.
This would have been caught by the pipe_builtin.cl test if that had used
the `spir-unknown-unknown` triple, so extend the test to use that
triple too.
