Support for the pipe built-in functions.
The pipe packet type can be user defined structure, we need to handle this in clang frontend.
This version is based on bader's opencl support patches. It transform all kinds of pipe type in anonymous pipe and identify the actual type by packet size in byte, and bitcast pointers to void* to get one function definition.
We may discuss how to handle these pipe built-in functions, I have tried few ways and none of them seems to be a perfect solution.
