nir/cf: Conditionally do block_add_normal_succs() in unlink_jump();
There is a bug where we mess up predecessors/successors due to the
ordering of unlinking/recreating edges/adding fake edges. In order to
fix that, I need everything in one routine.
However, calling block_add_normal_succs() isn't safe from
cleanup_cf_node() - it would crash trying to insert phi undefs.
So unfortunately I need to add a parameter.

nir/cf: Don't break outer-block successors in split_block_beginning().
Consider the following NIR:
block block_0;
/* succs: block_1 block_2 */
if (...) {
block block_1;
...
} else {
block block_2;
}
Calling split_block_beginning() on block_1 would break block_0's
successors: link_block() sets both successors of a block, so calling
link_block(block_0, new_block, NULL) would throw away the second
successor, leaving only /* succ: new_block */. This is invalid: the
block before an if statement must have two successors.
Changing the call to link_block(pred, new_block, pred->successors[0])
would correctly leave both successors in place, but because unlink_block
may shift successor[1] to successor[0], it may not preserve the original
order. NIR maintains a convention that successor[0] must point to the
"then" block, while successor[1] points to the "else" block, so we need
to take care to preserve this ordering.
This patch creates a new function that swaps out one successor for
another, preserving the ordering. It then uses this to fix the issue.

we need to emit the move but. However, if there is no swizzling, then the
mov is a no-op and we might as well not bother emitting it.

The value passed in count previously was "vertex after the last vertex

Looking at the code, many functions immediately do "count-start" to get
back the true count. That's just silly.
If it is better for the loops to be 'for (j = start; j < (start +
count); j++)', GCC will do that transformation.
NOTE: There is some strange formatting left by this patch. That was

one of NONE, FRAMEBUFFER_DEFAULT, TEXTURE, or RENDERBUFFER, identifying

All SKL SKUs except the lowest one which has half the L3 size actually have 384K

For once, I can explain how this mistake was made and how it was missed in
review... Historically when we enable a platform and put the production sizes,
you can simply look at the "smallest" SKU and see what its URB size is (and we
assumed it was the 1 slice variant). Since on newer platforms the URB sizes are
scaled automatically by HW, this was sufficient. On SKL, this is a bit different
as the lowest SKU actually has half of the L3 fused off. GT2 is the 1 slice (not
GT1) variant and it has 384K.
There are no Jenkins tests fixed (or regressions) and we don't expect any fixes
here because you can always run with less URB size.

i965: Turn BRW_MAX_MRF into a macro that accepts a hardware generation
There are some bug reports about shaders failing to compile in gen6
because MRF 14 is used when we need to spill. For example:
https://bugs.freedesktop.org/show_bug.cgi?id=86469
https://bugs.freedesktop.org/show_bug.cgi?id=90631
Discussion in bugzilla pointed to the fact that gen6 might actually have
24 MRF registers available instead of 16, so we could use other MRF
registers and avoid these conflicts (we still need to investigate why
some shaders need up to MRF 14 anyway, since this is not expected).
Notice that the hardware docs are not clear about this fact:
SNB PRM Vol4 Part2's "Table 5-4. MRF Registers Available in Device
Hardware" says "Number per Thread" - "24 registers"
However, SNB PRM Vol4 Part1, 1.6.1 Message Register File (MRF) says:
"Normal threads should construct their messages in m1..m15. (...)
Regardless of actual hardware implementation, the thread should
not assume th at MRF addresses above m15 wrap to legal MRF registers."
Therefore experimentation was necessary to evaluate if we had these extra
MRF registers available or not. This was tested in gen6 using MRF
registers 21..23 for spilling and doing a full piglit run (all.py) forcing
spilling of everything on the FS backend. It was also tested by doing
spilling of everything on both the FS and the VS backends with a piglit run
of shader.py. In both cases no regressions were observed. In fact, many of
these tests where helped in the cases where we forced spilling, since that
triggered the same underlying problem described in the bug reports. Here are
some results using INTEL_DEBUG=spill_fs,spill_vec4 for a shader.py run on
gen6 hardware:
Using MRFs 13..15 for spilling:
crash: 2, fail: 113, pass: 6621, skip: 5461
Using MRFs 21..23 for spilling:
crash: 2, fail: 12, pass: 6722, skip: 5461
This patch sets the ground for later patches to implement spilling
using MRF registers 21..23 in gen6.

In a later patch we will make BRW_MAX_MRF return a different value depending
on the hardware generation, but it is inconvenient to add a gen parameter
to the brw_reg functions only for the assertions, so move these to places where
we have the hardware generation available.
Ken suggested to add the asserts to brw_set_src0 and brw_set_dest since that
would make sure that we catch all uses of MRF registers, even those coming
from modules that generate native code directly, like blorp. Unfortunately,
this is very late in the process which can make things harder to debug, so add
asserts to the generator as well.

i965: Maximum allowed size of SEND messages is 15 (4 bits)
Until now we only used MRFs 1..15 for regular SEND messages, so the
message length could not possibly exceed the maximum size. Soon we'll
allow to use MRF registers 1..23 in gen6, so we need to be careful
not to build messages that can go beyond the limit. That could occur,
specifically, when building URB write messages, which we may need to
split in chunks due to their size. Previously we would simply go and
create a new message when we reached MRF 13 (since 13..15 were
reserved for spilling), now we also want to check the size of the
message explicitly.
Besides adding that condition to split URB write messages properly,
this patch also adds asserts in the generator. Notice that
brw_inst_set_mlen already asserts for this, but asserting in the
generators is easy and can make debugging easier in some cases.

* _mesa_gl_compressed_format_base_format() returns the base format.
As a side effect, we now check that we're in a desktop context when
determining support for the FXT1 and RGTC formats. This is in agreement
with our extension table and the glext headers.

nir/lower_tex: add support to clamp texture coords
Some hardware needs to clamp texture coordinates to [0.0, 1.0] in the
shader to emulate GL_CLAMP. This is added to lower_tex_proj since, in
the case of projected coords, the clamping needs to happen *after*
projection.
v2: comments/suggestions from Ilia and Eric, use txs to get texture size
and clamp RECT textures to their dimensions rather than [0.0, 1.0] to
avoid having to lower RECT textures to 2D.

i965/vec4: Change types as needed to propagate source modifiers using current instruction
SEL and MOV instructions, as long as they don't have source modifiers, are
just copying bits around. So those kind of instruction could be propagated
even if there are type mismatches. This is needed because NIR generates
integer SEL and MOV instructions whenever it doesn't know what else to
generate.
This commit adds support for copy propagation using current instruction
as reference.
Equivalent to commit 472ef9 but for vec4.
