With the advent of asynchronous maps, domain tracking doesn't make a
whole lot of sense. Buffers can be in use on both the CPU and GPU at
the same time. In order to avoid blocking, we stopped using set_domain
for asynchronous mappings, which means that the kernel's tracking has
lies. We can't properly track it in userspace either, as the kernel
can change domains on us spontaneously (for example, when un-swapping).
According to Chris Wilson, I915_GEM_SET_DOMAIN does the following:
1. pins the backing storage (acquiring pages outside of the
struct_mutex)
2. waits either for read/write access, including inter-device waits
3. updates the domain, clflushing as required
4. marks the object as used (for swapping)
5. turns off FBC/PSR/fancy scanout caching
Item (1) is not terribly important. Most BOs are recycled via the
BO cache, so they already have pages. Regardless, we fixed this
via an initial set_domain in the previous patch.
We implement item (2) with I915_GEM_WAIT. This has one downside:
we'll stall unnecessarily if we do a read-only mapping of a buffer
that the GPU is reading. I believe this is pretty uncommon. We
may want to extend the wait ioctl at some point.
Mesa already does item (3) itself. For cache-coherent buffers (most on
LLC systems), we don't need to do any clflushing - the CPU and GPU views
are coherent. For non-coherent buffers (most on non-LLC systems), we
currently only use the CPU for read-only maps, and we explicitly clflush
when necessary.
We don't care about item (4)...swapping has already killed performance.
Plus, with async maps, the kernel's domain tracking is already bogus,
so it can't do this accurately regardless.
Item (5) should be okay because we avoid cached maps of scanout buffers.

We had some caller using LLVMAddInstrAttributes, which couldn't be
converted to lp_add_function_attr, because attributes were only handled
for functions in this case, so fix this.
For llvm >= 4.0, this already works correctly.
(radeonsi seems to avoid setting call site attributes prior to llvm 4.0,
the patch then citing it doesn't work when calling intrinsics. But at
least for calling external functions we always used that, albeit only
for actual call attributes, not call parameter attributes, though some
quick test shows llvm seems to handle that as well. The attribute index
is sort of iffy though, since attribute 0 of the call is the actual function,
attribute 1 corresponds to the first parameter of the called function.)
(Verified with GALLIVM_DEBUG=dumpbc plus llvm-dis that the correct
attributes are shown for calls, both for llvm 4.0 and 3.3.)
