Previously, we failed to split constant arrays. Code such as
int[2] numbers = int[](1, 2);
would generates a whole-array assignment:
(assign () (var_ref numbers)
(constant (array int 4) (constant int 1) (constant int 2)))
opt_array_splitting generally tried to visit ir_dereference_array nodes,
and avoid recursing into the inner ir_dereference_variable. So if it
ever saw a ir_dereference_variable, it assumed this was a whole-array
read and bailed. However, in the above case, there's no array deref,
and we can totally handle it - we just have to "unroll" the assignment,
creating assignments for each element.
This was mitigated by the fact that we constant propagate whole arrays,
so a dereference of a single component would usually get the desired
single value anyway. However, I plan to stop doing that shortly;
early experiments with disabling constant propagation of arrays
revealed this shortcoming.
This patch causes some arrays in Gl32GSCloth's geometry shaders to be
split, which allows other optimizations to eliminate unused GS inputs.
The VS then doesn't have to write them, which eliminates the entire VS
(5 -> 2 instructions). It still renders correctly.
No other change in shader-db.

opt_constant_propagation.cpp contains constant folding code which can
actually do constant propagation in some cases. It was happily
propagating constants into the left-hand-side of assignments.
For example,
(assign () (var_ref temp) (constant ...))
would brilliantly be turned into:
(assign () (constant ...) (constant ....))
This is a bigger hammer than necessary - it prevents propagation
into the left-hand-side altogether. We could certainly do better
someday. Notably, the constant propagation pass itself already
takes this approach - it's just the constant propagation pass's
built-in constant folding code (which actually propagates, too)
that was broken.
No change in shader-db, but prevents regressions after future commits.
It seems plausible that this could be hit today, but I haven't seen it
happen.

Currently with the SetVertexBuffers optimization, we avoid emitting
redundant DXSetVertexBuffers commands. However, these buffers surfaces
will still need to be referenced, otherwise, in the case of linux,
the subsequent surface discard map will map to the existing mob instead
of a new one, causing rendering artifacts.
With this patch, we'll call resource_rebind() to reference the resources
even if we are avoiding the actual set command. This fixes the
rendering artifacts in the window title area running with unity in

This patch fixes three issues with vertex buffer references:
(1) Instead of copy the vertex buffer resource handles to the hw state
in the context structure, use pipe_resource_reference to properly
reference the vertex buffer resources in the context.
(2) Make sure to unbind those unused vertex buffer resources.
(3) Force to rebind the vertex buffer resources at the first draw of each
command buffer to make sure the vertex buffer resources are paged in.

This meant that the MCS address wasn't properly getting handled. Since we

ISL was being a bit too clever for its own good and lowering the format for
