ilo: fix gen6_3DSTATE_MULTISAMPLE()

mesa: check that uniform exists in glUniform* functions

Remap table for uniforms may contain empty entries when using explicit
uniform locations. If no active/inactive variable exists with given
location, remap table contains NULL.

v2: move remap table bounds check before existence check (Ian Romanick)

Generate a warning when not writing gl_Position with GLES.

With GLES we don't give any kind of warning in case we don't
write to gl_position. This patch makes changes so that we
generate a warning in case of GLES (VER < 300) and an error
in case of GL.

mesa: break up _mesa_swizzle_and_convert() to reduce compile time

This reduces gcc -O3 compile time to 1/4 of what it was on my system.
Reduces MSVC release build time too.

vc4: Bump maximum uniforms count to match other drivers.

We don't have any specific limits in the hardware, just like the other
GPUs, so match their behavior.  Fixes minmax_gles2 and several other
piglit tests relying on the specced uniform minmax values.
vc4: Bump maximum ARB program temporaries to match Intel/AMD.

This query has always been useless, but we could potentially reject
well-formed, runnable programs if we expose a value that's too low.
tgsi: don't print texture target for sample opcodes

sample opcodes don't encode a texture target, it would thus always
print UNKNOWN, which is not helpful (and wouldn't parse when giving
back the shader text to tgsi).

tgsi: accept offsets for sample opcodes too in the text parser

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.

gallivm: handle SAMPLE opcode in aos sampling

This is just a very limited version, in particular sampler and sampler view
index must be the same. It cannot handle any modifiers neither.
Works much the same as soa version otherwise, to figure out the target we
need to store the sampler view dcls.
While here, also handle (no-op) RET and get rid of a couple bogus deprecated
comments.

gallivm: attach DataLayout to module too, not just pass manager.

It looks like it was possible to attach it to both for a long time, however
since llvm r217548 attaching it to just the pass manager is no longer
sufficient and causes bugs (see http://llvm.org/bugs/show_bug.cgi?id=20903).

llvmpipe: Fix PIPE_FORMAT_Z32_FLOAT_S8X24_UINT handling for big-endian.

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.

util: Add big-endian layout for a number of formats.

This patch builds on 6c8f547f66e68b495c708f8ffcb67370caa5ffe8 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.
