The current gen_matypes logic assumes that the host compiler will produce
information that is useful for the target compiler. Unfortunately, this
is not the case whenever cross-compiling.
When we detect that we're cross-compiling and using GCC, use the target
compiler to produce assembly from the gen_matypes.c source, then process
it with a shell script to create a usable header. This is similar to how
the linux kernel creates its asm-offsets.c file.

Adds the dependencies of builtin_compiler as sources when cross
compiling instead of using libtool to share compilation with src/glsl.
The builtin_compiler executable is built for the host when cross
compiling so it doesn't make sense to share compilation with src/glsl
built for the target in this case.

Usually with fixed point renderbuffers clamping is done as part of conversion.
However, since we blend in float format, we essentially skip all conversion
steps pre-blend but since this is still a fixed point renderbuffer we must
still clamp the inputs in this case. Makes no difference for piglit though.
Obviously we could skip this if fragment color clamping is enabled, but a)
this is deprecated in OpenGL (d3d never had it) and b) we don't support it
natively so it gets baked into the shader.
Also add some comment about logic ops being broken for srgb, luckily no test
tries to do that as there's no easy fix...

We were fixing up the blend factor to ZERO, however this only works correctly
with fixed point render buffers where the input values are clamped to 0/1
(because src_alpha_saturate is min(As, 1-Ad) so can be negative with unclamped
inputs). Haven't seen any failure anywhere due to that with fixed point SNORM
buffers (which clamp inputs to -1/1) but it should apply there as well (snorm
blending is rare, even opengl 4.3 doesn't require snorm rendertargets at all,
d3d10 requires them but they are not blendable).
Doesn't look like piglit hits this though (some internal testing hits the
float case at least). (With legacy OpenGL we could theoretically still use the
fixup to zero if the fragment color clamp is enabled, but we can't detect that
easily since we don't support native clamping hence it gets baked into the
shader.)

- H.264 shows very occasional artifacts on a small fraction of videos
- MPEG2 + VDPAU shows frequent but small artifacts, which aren't there

Instead of just ignoring the srgb/linear conversions, simply call the
corresponding conversion functions, for all of pack/unpack/fetch,
both for float and unorm8 versions (though some don't make a whole
lot of sense, i.e. unorm8/unorm8 srgb/linear combinations).
Refactored some functions a bit so don't have to duplicate all the code
(there's a slight change for packing dxt1_rgb, as there will now be
always 4 components initialized and sent to the external compression
function so the same code can be used for all, the quite horrid and
ad-hoc interface (by now) should always have worked with that).

Historically, we indented grammar production rules with a single 8-space
tab, but code inside of blocks used Mesa's 3-space indents.
This meant when editing code, you had to use an 8-space tab for the
first level of indentation, and 3-spaces after that. Unless you
specifically configure your editor to understand this, it will get the
indentation wrong on every single line you touch, which quickly devolves
into a colossal waste of time.
It's also inconsistent with every other file in the entire project.
This patch removes all tabs and moves to a consistent 3-space indent.

The single remaining shift/reduce conflict was the classic ELSE problem:
292 selection_rest_statement: statement . ELSE statement
293 | statement .
ELSE shift, and go to state 479
ELSE [reduce using rule 293 (selection_rest_statement)]
$default reduce using rule 293 (selection_rest_statement)
The correct behavior here is to shift, which is what happens by default.
However, resolving it explicitly will make it possible to fail the build
on new errors, making them much easier to detect.
The classic way to solve this is to use right associativity:

I cut and pasted these comments from the Gen4 code during Ivybridge
enabling, and didn't understand what they meant at the time.
The data cache is NOT the same as the sampler cache on Ivybridge.
The sampler cache has L1 and L2 caches in addition to the L3 cache,
while data port messages to the "data cache" hit L3 directly.
This means that the sampler domain is technically wrong, but we stopped
caring about read/write domains quite a while ago. The kernel just
flushes all the caches at the end of each batchbuffer, and our render to
texture code flushes the sampler caches when necessary.

Presumably, this comment exists to justify the usage of
I915_GEM_DOMAIN_SAMPLER for this relocation. At one point, this was
necessary to ensure that the right flushing was done to keep caches
coherent. These days, the kernel just flushes everything, so I don't
think it matters.
Still, the comment is interesting, so leave it in place.

Only support 4x8bit srgb formats (rgba/rgbx plus swizzle), 24bit formats never
worked anyway in the blend code and are thus disabled, and I don't think anyone
is interested in L8/L8A8. Would need even more hacks otherwise.
