[Libclc-dev] [PATCH] r600: Initial support

[tstellar at gmail.com]

From: Tom Stellard <thomas.stellard at amd.com>

This includes a get_global_id() implementation and function stubs for
the other workitem and synchronization functions.
---

Thanks for the tips, Peter.  I've left all the workitem functions, besides
get_global_id(), in the header files for now, just because I haven't
implemented enough in the backend for them to work.  I'll eventually
move them all to the lib directory, just like I did with get_global_id().
