texture buffer sizes. But this seems to be enough for stk gl31 render

This shows up with a glamor shader, which does a TXF and uses the result
for conditional kill. Before we wouldn't group the fanin (collect)
neighbors which need to be allocated adjacently at RA, resulting in
badness.

together. Also, introduce is_ir3() for things that are more specific to
the compiler / shader-ISA than to the gpu generation.

Because we build here an array format, we don't need to swap the
bytes for big endian.
If it isn't an array format, the bytes will be swapped in

Before, if we encountered an array format of 0 on a BE system, we would
flip all the channels even though it's an invalid format. This would
result in a mostly invalid format with a swizzle of yyyy or wwww. Instead,
we should just return 0 if the array format stashed in the format info is
invalid.
Cc: "10.6 10.5" <mesa-stable@lists.freedesktop.org>
The swizzle defines where in the format you should look for any given
channel. When we flip the format around for BE targets, we need to change
the destinations of the swizzles, not the sources. For example, say the
format is an RGBX format with a swizzle of xyz1 on LE. Then it should be
wzy1 on BE; however, the code as it was before, would have made it 1zyx on
BE which is clearly wrong.

r600 currently has 73 atoms and looping through their dirty flags has
become costly because checking each flag requires a pointer
dereference before the read. To avoid having to do that add additional
bitfield which can be checked really quickly thanks to tzcnt instruction.
id field was added to struct r600_atom but that doesn't affect memory
usage for both 32 and 64 bit CPUs because it was stuffed into padding.
The performance improvement is ~2% for benchmarks that can have FPS in
the thousands but is hardly measurable in "real" programs.

This fixes the spec@arb_shader_image_load_store@invalid index bounds
piglit tests on IVB, which were causing a GPU hang and then a crash
due to the invalid binding table index result of the array index
calculation. Other generations seem to behave sensibly when an
invalid surface is provided so it doesn't look like we need to care.

Define bitfield packing, unpacking and type conversion operations in
terms of which the image format conversion code will be implemented.
These don't directly know about image formats: The packing and
unpacking functions take a 4-tuple of bit shifts and a 4-tuple of bit
widths as arguments, determining the bitfield position of each
component. Most of the remaining functions perform integer, fixed
point normalized, and floating point type conversions, mapping between
a target type with per-component bit widths given by a parameter and a
matching native representation of the same type.

Define a function to calculate the memory address of the image
location given by a vector of coordinates. This is required in cases
where we need to fall back to untyped surface access, which take a raw
memory offset and know nothing about surface coordinates, type
conversion or memory tiling and swizzling. They are still useful
because typed surface reads don't support any 64 or 128-bit formats on
IVB, and they don't support any 128-bit formats on HSW and BDW.
The tiling algorithm is implemented based on a number of parameters
which are passed in as uniforms and determine whether the surface
layout is X-tiled, Y-tiled or untiled. This allows binding surfaces
of different tiling layouts to the pipeline without recompiling the
program.

These utility functions check whether an image access is valid.
According to the spec an invalid image access should have no effect on
the image and yield well-defined results. Typically the hardware
implements correct bounds and surface checking by itself, but in some
cases (typed atomics on IVB and untyped messages elsewhere) we need to
implement it in software to work around lacking hardware support.
