I've wondered whether we ought to put these in src/intel/oa, for
possible future use in the Vulkan driver.  Or, just to get all the
OA related XML, scripts, and generated C files in their own directory
(since there end up being quite a few of them).

But it does seem a bit speculative...so...this is fine too.
