For the first use of a buffer, we will only need the temporary
resource in the case that a user wants to write/map to this buffer.
But in the cases where the user creates a buffer to act as an
output of a kernel, then we were creating an unneeded resource,
because it will contain garbage, and would be copied to the pool,
and destroyed when promoting.
This patch avoids the creation and copies of resources in
this case.

The important part is the change of the condition to <= 0. Otherwise the loop
gets stuck never actually growing the pool.
The change in the aux-need calculation guarantees max 2 iterations, and
avoids wasting memory in case a smaller item can't fit into a relatively larger
pool.

The dst pointer needs to be initialized after any calls to

nouveau screens are reused for the same device node. However in the
scenario where we create screen 1, screen 2, and then delete screen 1,
the surrounding code might also close the original device node. To
protect against this, dup the fd and use the dup'd fd in the
nouveau_device. Also tell the nouveau_device that it is the owner of the
fd so that it will be closed on destruction.
Also make sure to free the nouveau_device in case of any failure.

Previously, if we had something like:
gl_ViewportIndex = idx;
for(int i = 0; i < gl_in.length(); i++) {
gl_Position = gl_in[i].gl_Position;
EmitVertex();
}
EndPrimitive();
The right viewport index would not be set on the primitive because the
last vertex is the provoking one. However blob drivers appear to move
the gl_ViewportIndex write into the for loop, allowing the application
to be ignorant of this detail.
While the application is technically wrong here, because the blob does
it and other drivers appear to implicitly work this way as well, we add
a buffer register that viewport index writes go into, which is then
exported before every EmitVertex() call.
This fixes the remaining piglit tests in ARB_viewport_array for nv50/nvc0.

The old logic would let all negative values go through unclamped, with
potentially disastrous results (probably trying to fetch viewport values
from random memory locations). GL has undefined rendering for vp indices
outside valid range but that's a bit too undefined...
(The logic is now the same as in llvmpipe.)

Blob driver seems to need WFI in some cases after CP_EVENT_WRITE,
implying that this is asynchronous and should reset needs_wfi.
Also, CP_INVALIDATE_STATE seems to need WFI. But CP_LOAD_STATE
does not.
The blob driver also puts WFIs before writing GRAS_CL_VPORT registers.
The latter may be a work-around, as these registers should be banked/
context registers. I haven't yet found a lockup that this averts, but
I expect viewport to change infrequently so out of paranoia I will
keep these for now.

This patch changes completely the way buffers are added to the
compute_memory_pool. Before this, whenever we were going to
map a buffer or write to or read from it, it would get placed
into the pool. Now, every unallocated buffer has its own
r600_resource until it is allocated in the pool.
NOTE: This patch also increase the GPU memory usage at the moment
of putting every buffer in it's place. More or less, the memory
usage is ~2x(sum of every buffer size)

Previously llvm detected cpu features automatically when the execution engine
was created (based on host cpu). This is no longer the case, which meant llvm
was then not able to emit some of the intrinsics we used as we didn't specify
any sse attributes (only on avx supporting systems this was not a problem since
despite at least some llvm versions enabling it anyway we always set this
manually). So, instead of trying to figure out which MAttrs to set just set
MCPU.
