If we're in some conditional or loop we must not return, or the code
after the condition is never executed.
(v2): And, we also can't just continue as nothing happened, since the
mask update code would later check if we actually have a mask, so we
need to remember that there was a return in main where we didn't exit
(to illustrate this, a ret in a if clause would cause a mask update
which is still ok as we're in a conditional, but after the endif the
mask update code would drop the mask hence bringing execution back to
pixels which should have their execution mask set to zero by the ret).
Thanks to Christoph Bumiller for figuring this out.

(cherry picked from commit f70c385351)
Fast depth clears have the same depth/stencil alignment requirements
as other drawing operations. Therefore, we need to call
brw_workaround_depthstencil_alignment() from both the clear and
drawing paths.
Without this fix, we get image corruption if the following conditions
hold: (a) the first ever drawing operation to a depth miplevel (or the
first drawing operation after having used the texture for sampling) is
a clear, (b) the depth miplevel has a size that is eligible for fast
depth clears, and (c) the depth miplevel has an offset within the
miptree that isn't 8x8 aligned.
Fixes piglit "depthstencil-render-miplevels" tests with size 273.

We were handling the the dependency workaround for the first written reg
of a send preceding the one we're fixing up, but didn't consider the other
regs. Thus if you had two sampler calls that got allocated to the same
set of regs, one might, rarely, ovewrite the other. This was occurring in
XBMC's GLSL shaders.

We were allowing a compressed instruction to write a register that
contained the last use of a uniform pull constant (either UBO load or push
constant spillover), so it would get half its values smashed.
Since we need to see the actual instruction to decide this, move the
pre-gen6 pixel_x/y logic here, which should improve the performance of
register allocation since virtual_grf_interferes() is called more than
once per instruction.

We advertise a max texture/surfaces size of 8K x 8K but the old values
for these limits didn't actually allow us to handle that surface size.
For 8K x 8K we'll have 16384 bins. Each bin needs at least one cmd_block
object which was 2192 bytes in size. Since 16384 * 2192 exceeded
LP_SCENE_MAX_SIZE we'd silently fail in lp_scene_new_data_block() and not
draw the complete scene.
By reducing CMD_BLOCK_MAX to 29 we get nice 512-byte cmd_blocks. And
by increasing LP_SCENE_MAX_SIZE to 9 MB we can allocate enough command
blocks for 8K x 8K, plus a few regular data blocks.
Fixes the (improved) piglit fbo-maxsize test.

On cayman, 128bpp surfaces require non_disp ordering for hw
access to both linear and tiled surfaces. When we use the 3D
engine we can set the non_disp ordering on both the tiled and
linear sides (via CB or texture), but when we use the DMA
engine, we can only set the non_disp ordering on the tiled
side, so after a L2T operation with the DMA engine, the data
ends up in the wrong order on the tiled side.
