We also think InstCombine is a good place to put this optimization, if we

[LLVMdev] Reducing Generic Address Space Usage
This is a follow-up discussion on
http://lists.cs.uiuc.edu/pipermail/cfe-commits/Week-of-Mon-20140324/101899.html.
The front-end change was already pushed in r204677, so we want to continue
with the IR optimization.
In general, we want to write an IR pass to convert generic address space
usage to non-generic address space usage, because accessing the generic
address space in CUDA and OpenCL is
