Luminance is the least-significant byte of the uint16, rather than the
lowest byte in memory. Other parts of mesa already handle this correctly
for big-endian, and swrast already handles other MESA_FORMAT_x8y8 formats
correctly. This case was just an odd-one-out.

MESA_FORMAT_R8G8B8X8_SNORM used a function called unpack_X8B8G8R8_SNORM
while MESA_FORMAT_R8G8B8X8_SRGB used a function called unpack_R8G8B8X8_SRGB.
This patch renames the SNORM function to have the same order as the
MESA_FORMAT name, like the SRGB function does.

This gets a ton of piglit working that crashes in waffle context
management stuff otherwise. Actually supporting mismatched FB sizes is at
best going to require some more load/store generals for color buffers, but
if I can't manage to do that I'll want to just have state_tracker reject
those FBOs as unsupported, rather than deny GL 2.1.
Previously, we would get a trailing ', ' which looked strange.

The goal here is to have an argument for the depth write opcode so that I
can do computed depth. In the process, this makes the calculations that
will be emitted more obvious in the QIR.
Commit afe3d1556f (i965: Stop doing
remapping of "special" regs.) stopped remapping delta_x/delta_y, and
additionally stopped considering them always-live. We later realized
delta_x was used in register allocaiton, so we actually needed to remap
it, which was fixed in commit 23d782067a
(i965/fs: Keep track of the register that hold delta_x/delta_y.).
However, that commit didn't restore the "always consider it live" part.
If all the code using delta_x was eliminated, fs_visitor::delta_x would
be left pointing at its old register number. Later code in register
allocation would handle that register number specially...even though it
wasn't actually delta_x.
To combat this, set delta_x/y to BAD_FILE if they're eliminated, and
check for that.

This patch builds on 6c8f547f66 and
previous patches by allowing u_format.csv to specify separate big-endian
and little-endian layouts. It then uses this to specify the correct layouts
for various depth/stencil formats. Later patches handle other formats.
To recap, the idea is that u_format.csv lists the channels for an N-byte
value as though it were an N-byte integer. For little-endian targets
the channels are listed starting at the least-significant bit of the
integer while for big-endian targets the channels are listed starting
at the most-significant bit. This means that for something like
PIPE_FORMAT_B8G8R8A8_UNORM (blue in first byte of memory, alpha in last
byte of memory) the orders are the same for both endiannesses. But for
something like PIPE_FORMAT_S8_UINT_Z24_UNORM, where the stencil is in
the least significant byte of a 32-bit integer, there need to be separate
channel definitions for each endianness.
The effect of this patch is to make the affected PIPE_FORMAT_*s have
the same layout as the associated MESA_FORMAT_*s for big-endian.
The MESA_FORMAT_*s are already handled correctly.
Fixes various piglit tests on z. No regressions on x86_64.

llvmpipe treats PIPE_FORMAT_Z32_FLOAT_S8X24_UINT as a bit of a special case,
handling it as two 32-bit pieces rather than a single 64-bit block:
/* 64bit d/s format is special already extracted 32 bits */
total_bits = format_desc->block.bits > 32 ? 32 : format_desc->block.bits;
The format_desc describes the whole 64-bit block, so the z shift
will be 32 for big-endian. But since we're accessing the z channel
as a 32-bit value rather than a 64-bit value, we need to mask the shift
with 31.

This is just a very limited version, in particular sampler and sampler view

Works much the same as soa version otherwise, to figure out the target we

sample opcodes are a little oddly represented in the opcode_info, since
they don't count as texture instructions - they don't have valid target
information, but they may have offsets (unlike "ordinary" texture
instructions, the texture token may be optional for them).
So just make sure with these opcodes the optional offsets are accepted.
