Test Case for SLG InitFrameBuffer Kernel

I've tracked down where slg4 is segfaulting on my machine currently. The
InitFrameBuffer Kernel is not being compiled/invoked correctly. It's a very
simple kernel that works fine IF you split the kernel out on its own, but when
you embed the kernel within a large source file (~8600 lines), the compilation
process seems to break.

There's an #if 0 at line 44 of this test case that will, when flipped, show how
the kernel itself is fine, but the other non-invoked code causes it to break.

I'm assuming that we've got some buffer/iterator in clover or LLVM which is
breaking on large CL source files.
