(cherry picked from commit b0b5430322)
Buffers in the MANAGED pool are supposed to have the content in a ram buffer,
a copy in VRAM if there is enough memory (driver manages memory and decide when
to delete the buffer in VRAM).
This is not implemented properly in nine, and a VRAM copy is going to be created
when the RAM memory is filled, and the VRAM copy will get synced with the RAM
memory updates.
Due to some issues (in the implementation or in app logic), it can happen
we try to create a sampler view of the resource while we haven't created the
VRAM resource. This hack creates the resource when we hit this case, which prevents
crashing, but doesn't help with the resource content.
This fixes several games crashing at launch.

(cherry picked from commit c5be9c126d)
Gen4 hardware appears to GPU hang frequently when using Chromium, and
also when running 'glmark2 -b ideas'. Most of the error states contain
3DPRIMITIVE commands in quick succession, with very few state packets
between them - usually VERTEX_BUFFERS/ELEMENTS and CONSTANT_BUFFER.
I trimmed an apitrace of the glmark2 hang down to two draw calls with a
glUniformMatrix4fv call between the two. Either draw by itself works
fine, but together, they hang the GPU. Removing the glUniform call
makes the hangs disappear. In the hardware state, this translates to
removing the CONSTANT_BUFFER packet between the two 3DPRIMITIVE packets.
Flushing before emitting CONSTANT_BUFFER packets also appears to make
the hangs disappear. I observed a slowdown in glxgears by doing it all
the time, so I've chosen to only do it when BRW_NEW_BATCH and
BRW_NEW_PSP are unset (i.e. we haven't done a CS_URB_STATE change or
already flushed the whole pipeline).
I'd much rather understand the problem, but at this point, I don't see
how we'd ever be able to track it down further. We have no real tools,
and the hardware people moved on years ago. I've analyzed 20+ error
states and read every scrap of documentation I could find.

I haven't yet encountered any overflow bugs in the wild along this

bug in a line of code that looks very similar to pointer arithmetic in

This patch conceptually applies the same fix as in b69c7c5dac. Instead
of retyping the variables, though, this patch adds some casts. (I tried
to retype the variables as ptrdiff_t, but it quickly got very messy. The
casts are cleaner).

(cherry picked from commit 48094d0e65)
This is a partial revert of c89306983c.
It split the {start,base}_vertex_location handling into several steps:
1. Set brw->draw.start_vertex_location = prim[i].start
and brw->draw.base_vertex_location = prim[i].basevertex.
(This happened once per _mesa_prim, in the main drawing loop.)
2. Add brw->vb.start_vertex_bias and brw->ib.start_vertex_offset
appropriately. (This happened in brw_prepare_shader_draw_parameters,
which was called just after brw_prepare_vertices, as part of state
upload, and only happened when BRW_NEW_VERTICES was flagged.)
3. Use those values when emitting 3DPRIMITIVE (once per _mesa_prim).
If we drew multiple _mesa_prims, but didn't flag BRW_NEW_VERTICES on
the second (or later) primitives, we would do step #1, but not #2.
The first _mesa_prim would get correct values, but subsequent ones
would only get the first half of the summation.
The reason I originally did this was because I needed the value of
gl_BaseVertexARB to exist in a buffer object prior to uploading
3DSTATE_VERTEX_BUFFERS. I believed I wanted to upload the value
of 3DPRIMITIVE's "Base Vertex Location" field, which was computed
as: (prims[i].indexed ? prims[i].start : prims[i].basevertex) +
brw->vb.start_vertex_bias. The latter value wasn't available until
after brw_prepare_vertices, and the former weren't available in the
state upload code at all. Hence the awkward split.
However, I believe that including brw->vb.start_vertex_bias was a
mistake. It's an extra bias we apply when uploading vertex data into
VBOs, to move [min_index, max_index] to [0, max_index - min_index].
>From the GL_ARB_shader_draw_parameters specification:
"<gl_BaseVertexARB> holds the integer value passed to the <baseVertex>
parameter to the command that resulted in the current shader
invocation. In the case where the command has no <baseVertex>
parameter, the value of <gl_BaseVertexARB> is zero."
I conclude that gl_BaseVertexARB should only include the baseVertex
parameter from glDraw*Elements*, not any internal biases we add for
optimization purposes.
With that in mind, gl_BaseVertexARB only needs prim[i].start or
prim[i].basevertex. We can simply store that, and go back to computing
start_vertex_location and base_vertex_location in brw_emit_prim(), like
we used to. This is much simpler, and should actually fix two bugs.
