pan/midgard: Schedule before RA
This is a tradeoff.
Scheduling before RA means we don't do RA on what-will-become pipeline
registers. Importantly, it means the scheduler is able to reorder
instructions, as registers have not been decided yet.
Unfortunately, it also complicates register spilling, since the spills
themselves won't get bundled optimally and we can only spill twice per
ALU bundle (only one spill per bundle allowed here). It also prevents us
from eliminating dead moves introduced by register allocation, as they
are not dead before RA. The shader-db regressions are from poor spilling
choices introduced by the new bundling requirements. These could be
solved by the combination of a post-scheduler (to combine adjacent
spills into bundles) with a VLIW-aware spill cost calculation.
Nevertheless, the change is small enough that I feel it's worth it to
eat a tiny shader-db regression for the sake of flexibility.

pan/midgard: Add scheduling barriers
Scheduling occurs on a per-block basis, strongly assuming that a given
block contains at most a single branch. This does not always map to the
source NIR control flow, particularly when discard intrinsics are
involved. The solution is to allow scheduling barriers, which will
terminate a block early in code generation and open a new block.
To facilitate this, we need to move some post-block processing to a new
pass, rather than relying hackily on the current_block pointer.
This allows us to cleanup some logic analyzing branches in other parts
of the driver us well, now that the MIR is much more well-formed.

nir/range-analysis: Handle constants in nir_op_mov just like nir_op_bcsel
I discovered this while looking at a shader that was hurt by some other
work I'm doing. When I examined the changes, I was confused that one
instance of a comparison that was used in a discard_if was (incorrectly)
eliminated, while another instance used by a bcsel was (correctly) not
eliminated. I had to use NIR_PRINT=true to see exactly where things
when wrong.
A bunch of shaders in Goat Simulator, Dungeon Defenders, Sanctum 2, and
Strike Suit Zero were impacted.

nir/range-analysis: Fix incorrect fadd range result for (ne_zero, ne_zero)
Found by inspection. I tried really, really hard to make a test case
that would trigger this problem, but I was unsuccesful. It's very hard
to get an instruction to produce a ne_zero result without ne_zero
sources. The most plausible way is using bcsel. That proves
problematic because bcsel interprets its sources as integers, so it
cannot currently be used to "clean" values for floating point
instructions.

iris: Don't auto-flush/dirty on transfer unmap for coherent buffers
When u_upload_mgr fills up a buffer, it unmaps and destroys it. Our
unmap function was automatically performing the equivalent of a
FlushMappedBufferRange call in this case. Because the buffer mapping
is persistent and coherent, we don't actually do any flushing when we
do the rest of the writes to the buffer - we were just doing one final
one at the end. But we would be using the uploaded contents on the
GPU the whole time.
This certainly shouldn't be necessary for streaming buffers, and if
such flushing and dirtying is necessary for coherent buffers, this is
wildly insufficient.
Drops a small number of constant packets and PIPE_CONTROL flushes from
most benchmarks that I've looked at. Doesn't seem to make much of an
impact on performance, however.
Thanks to Felix Degrood for noticing that we were emitting more
3DSTATE_CONSTANT_* packets than we needed to.

that the HW doesn't get to select between the min and mag filters.
Setting MIPFILTER_LINEAR_FAR appears to force non-mipmap filtering.
Fixes all failures in dEQP-GLES2.functional.texture.filtering.2d.*

intel/compiler: Request bitfield_reverse lowering on pre-Gen7 hardware
See the previous commit for the explanation of the Fixes tag.
Hurts 21 shaders in shader-db. All of the hurt shaders are in Unreal

nir/algrbraic: Don't optimize open-coded bitfield reverse when lowering is enabled
This caused a problem on Sandybridge where an open-coded
bitfieldReverse() function could be optimized to a
nir_op_bitfield_reverse that would generate an unsupported BFREV
instruction in the backend. This was encountered in some Unreal4 tech
demos in shader-db. The bug was not previously noticed because we don't
actually try to run those demos on Sandybridge.
The fixes tag is a bit a lie. The actual bug was introduced about
26,000 commits earlier in
371c4b3c48f ("nir: Recognize open-coded
bitfield_reverse."). Without the NIR lowering pass, the flag needed to
avoid the optimization does not exist. Hopefully nobody will care to
fix this on an earlier Mesa release.

gallium: Fix big-endian addressing of non-bitmask array formats.
The formats affected are:
- LA x (16_FLOAT, 32_FLOAT, 32_UINT, 32_SINT)
- R8G8B8 x (UNORM, SNORM, SRGB, USCALED, SSCALED, UINT, SINT)
- RG/RGB/RGBA x (64_FLOAT, 32_FLOAT, 16_FLOAT, 32_UNORM, 32_SNORM,

- RGBx32 x (FLOAT, UINT, SINT)
- RA x (16_FLOAT, 32_FLOAT, 32_UINT, 32_SINT)
The updated st_formats.c unit test checks that the formats affected by
this change are all array formats in the equivalent Mesa format (if
any). Mesa's array format definition is clear: the value stored is an
array (increasing memory address) of values of the channel's type.
It's also the only thing that makes sense for the RGB types, or very
large types like RGBA64_FLOAT (A should not move to the low address
because the cpu is BE).
