As the alignment requirements can be 32 KiB or more, also adding
an aligned buffer creation function.
DCC is disabled for textures that can be shared as sharing the
DCC buffers has not been implemented yet.

Out of 7063 shaders from my shader-db:
- 6564 (93%) shaders don't have any state parameters.
- 347 (5%) shaders have 1 state parameter for WPOS lowering.
- The remaining 2% have more state parameters, usually matrices.

The edgeflag comes in as ubyte with glEdgeFlagPointer but as float with
plain immediate glEdgeFlag. Avoid reading bytes that weren't meant for
the edgeflag in the pointer case.
Fixes intermittent failures with gl-2.0-edgeflag piglit (and valgrind
complaints about reading uninitialized memory).

We can't do this all the time, because you want blending to be done in
linear space, and sRGB would lose too much precision being done in 4x8.
The win on instructions is pretty huge when you can, though.
total uniforms in shared programs: 32065 -> 32168 (0.32%)
uniforms in affected programs: 327 -> 430 (31.50%)
total instructions in shared programs: 92644 -> 89830 (-3.04%)
instructions in affected programs: 15580 -> 12766 (-18.06%)
Improves openarena performance at 1920x1080 from 10.7fps to 11.2fps.
This corresponds to instructions used on vc4 for its blending inside of
shaders. I've seen these opcodes on other architectures before, but I
think it's the first time these are needed in Mesa.
v2: Rename to 'u' instead of 'i', since they're all 'u'norm (from review

Now that we don't read each component one-by-one, we don't need the
temoprary vgrf for the offset. More importantly, this register was type
UD while the nir source was type D. This broke copy propagation and left
a redundant MOV in the generated code.

The scalar destination registers break copy propagation. Instead compute
the results to a regular register and then reference a component when we
later use the result as a source.

The destination for SHADER_OPCODE_FIND_LIVE_CHANNEL is always a UD
register. When we replace the opcode with a MOV, make sure we use a UD
immediate 0 so copy propagation doesn't bail because of non-matching
types.

We always set the mask to 0xffff, which is what it defaults to when no
header is present. Let's drop the header instead.
v2: Only remove header for untyped reads. Typed reads always need the
header.

Commit f17b78 added an alternative reads_flag(channel) that returned
if the instruction was reading a specific channel flag. By mistake it
only took into account the predicate, but when the opcode is
VS_OPCODE_UNPACK_FLAGS_SIMD4X2 there isn't any predicate, but the flag
are used.
That mistake caused some regressions on old hw. More information on
this bug:

This is a little bit like the mprotect-based fencing I've experimented
with, but it's simple and low overhead. The downside is that only catches
writes, not reads.
It didn't catch any bad writes on a current piglit run, but may be useful
in the future.
Move scratch_size out of ilo_state_shader_kernel_info and
ilo_state_compute_interface_info. A scratch space is shared by all
kernels/interfaces. Update builder to emit relocs for scratch bos.
Location has never been able to be a negative value because it has
always been validated in the parser.
Also the linker doesn't check for negatives like the comment claims.

virgl/vtest is a swrast driver that allows the
virgl acceleration to be tested without having
a virtual machine.
The backend has a unix socket server that
this connects to.
This is run by setting
LIBGL_ALWAYS_SOFTWARE=y
GALLIUM_DRIVER=virpipe
In this mode all renderering is sent over
a socket to the remote renderer, and the
results are readback and copies to the screen
using drisw. This works well enough to develop
new features and to help debug.
