On 64 bits platforms, some atomic operations like __sync_fetch_and_add()
have constant time, but on 32 bits platforms they are implemented with a
loop and might take much longer.
Additionally, it seems like if their operands are not aligned to 64
bits, they also require extra memory accesses. From the Intel
Architecture's Developer Manual Vol. 1, 4.1.1:
"A word or doubleword operand that crosses a 4-byte boundary or a
quadword operand that crosses an 8-byte boundary is considered
unaligned and requires two separate memory bus cycles for access."
Forcing the u64 field to be aligned to 64 bits seems to make the unit
tests that are stressing this finish much faster.

From the MEDIA_VFE_STATE docs:
"Starting with this configuration, the Maximum Number of Threads must
be set to (#EU * 8) for GPGPU dispatches.
Although there are only 7 threads per EU in the configuration, the
FFTID is calculated as if there are 8 threads per EU, which in turn
requires a larger amount of Scratch Space to be allocated by the
driver."
It's pretty clear that we need to increase this for scratch address
calculations, because the FFTID has a certain bit-pattern. The quote
above seems to indicate that we should increase the actual thread count
programmed in MEDIA_VFE_STATE as well, but we think the intention is to
only bump the scratch space.

This reverts commit 729de1488f.
It turns out that, although the register is in the logical context,
it isn't whitelisted, so we can't actually write it from userspace
batch buffers. The write just becomes a noop, which is why we saw
no performance changes.
I manually whitelisted it, and still observed no performance gains, but
it did regress KHR-GL46.texture_cube_map_array.color_depth_attachments
on the iris driver. So we might need to fix something before enabling
this. To prevent it randomly getting turned on should the kernel ever
whitelist this register, we revert the patch for now.
This effectively breaks the instance dispatch table in 2 with entry
points using a physical device as first argument getting their own
dispatch table.
As a result we now have to check instance & physical device dispatch
table instead of just the instance dispatch table before.

However, gen8 doesn't support bindless images and thus needs to report a

In the case where the stencil clear is nicely aligned, we can clear
stencil much more efficiently by mapping it as a wide format (say
RGBA32_UINT) and blasting out the stencil clear value with a repclear.
On Unigine Heaven, this makes one stencil clear go from non-trivial to
unnoticeable when looking at per-draw timings.
In order for this change to work properly, ANV needs to do a bit more
flushing around depth and stencil clears. i965 and iris already have
the cache tracking logic to handle this so no changes are required
there.

This bit redirects the state cache from the unified/RO sections of the
L3 cache to the "CS command buffer" section of the cache, which would
be set up via TCCNTLREG. The documentation says:
"Additionaly, this redirection should be enabled only if there is a
non-zero allocation for the CS command buffer section."
We don't allocate any cache to the CS command buffer section, so
enabling this redirection effectively disabled the state cache.
The Windows driver only sets up that section when using POSH, which
we do not currently use. So, leave it unallocated and disable the
redirection to get a functional state cache again.

On commit f6e7de41d7, we started emitting 3DSTATE_LINE_STIPPLE as part

regression of about 9-10% on Dota2.
This commit makes anv_dynamic_state_copy() return a mask with only the
state that has changed when copying it. 3DSTATE_LINE_STIPPLE won't be
emitted anymore unless it has changed, fixing the problem above.
