b909ac350f intel/compiler: Rename vec4 state URB opcodes to have VEC4_ prefix
An argument could be made that all stage-specific opcodes for vec4
stages should be prefixed with VEC4_ like the stage-agnostic opcodes.
I'll leave those additional sed jobs for another day.

    egrep -lr '(VS|GS|TCS)_OPCODE_URB_WRITE' src |\
    while read f; do
        sed --in-place 's/\(VS\|GS\|TCS\)_OPCODE_URB_WRITE/VEC4_\1_OPCODE_URB_WRITE/g' $f
    done

    egrep -lr 'T.S_OPCODE[_A-Z]*URB_OFFSETS' src |\
    while read f; do
        sed --in-place 's/\(T.S_OPCODE[_A-Z]*URB_OFFSETS\)/VEC4_\1/g' $f
    done

d05f7b4a2c intel: fix INTEL_DEBUG environment variable on 32-bit systems
INTEL_DEBUG is defined (since 4015e1876a) as:

 #define INTEL_DEBUG __builtin_expect(intel_debug, 0)

which unfortunately chops off upper 32 bits from intel_debug
on platforms where sizeof(long) != sizeof(uint64_t) because
__builtin_expect is defined only for the long type.

Fix this by changing the definition of INTEL_DEBUG to be function-like
macro with "flags" argument. New definition returns 0 or 1 when
any of the flags match.

Most of the changes in this commit were generated using:
for c in `git grep INTEL_DEBUG | grep "&" | grep -v i915 | awk -F: '{print $1}' | sort | uniq`; do
    perl -pi -e "s/INTEL_DEBUG & ([A-Z0-9a-z_]+)/INTEL_DBG(\1)/" $c
    perl -pi -e "s/INTEL_DEBUG & (\([A-Z0-9_ |]+\))/INTEL_DBG\1/" $c
done
but it didn't handle all cases and required minor cleanups (like removal
of round brackets which were not needed anymore).

517005b4cf i965: Use NIR to lower legacy userclipping.
This allows us to drop legacy userclip plane handling in both the vec4
and FS backends, and simplifies a few interfaces.

v2 (Jason Ekstrand):
 - Move brw_nir_lower_legacy_clipping to brw_nir_uniforms.cpp because
   it's i965-specific.
 - Handle adding the params in brw_nir_lower_legacy_clipping
 - Call brw_nir_lower_legacy_clipping from brw_codegen_vs_prog

14781e2122 intel/compiler: Add a "base class" for program keys
Right now, all keys have two things in common: a program string ID and a
sampler_prog_key_data.  I'd like to add another thing or two and need a
place to put it.  This commit adds a new brw_base_prog_key struct which
contains those two common bits.

74e1d6e20c i965: Drop support for the legacy SNORM -> Float equation.
Older OpenGL defines two equations for converting from signed-normalized
to floating point data.  These are:

    f = (2c + 1)/(2^b - 1)                (equation 2.2)
    f = max{c/2^(b-1) - 1), -1.0}         (equation 2.3)

Both OpenGL 4.2+ and OpenGL ES 3.0+ mandate that equation 2.3 is to be
used in all scenarios, and remove equation 2.2.  DirectX uses equation
2.3 as well.  Intel hardware only supports equation 2.3, so Gen7.5+
systems that use the vertex fetcher hardware to do the conversions
always get formula 2.3.

This can make a big difference for 10-10-10-2 formats - the 2-bit value
can represent 0 with equation 2.3, and cannot with equation 2.2.

Ivybridge and older were using equation 2.2 for OpenGL, and 2.3 for ES.
Now that Ivybridge supports OpenGL 4.2, this is wrong - we need to use
the new rules, at least in core profile.  That would leave Gen4-6 doing
something different than all other hardware, which seems...lame.

With context version promotion, applications that requested a pre-4.2
context may get promoted to 4.2, and thus get the new rules.  Zero cases
have been reported of this being a problem.  However, we've received a
report that following the old rules breaks expectations.  SuperTuxKart
apparently renders the cars red when following equation 2.2, and works
correctly when following equation 2.3:

https://github.com/supertuxkart/stk-code/issues/2885#issuecomment-353858405

So, this patch deletes the legacy equation 2.2 support entirely, making
all hardware and APIs consistently use the new equation 2.3 rules.

If we ever find an application that truly requires the old formula, then
we'd likely want that application to work on modern hardware, too.  We'd
likely restore this support as a driconf option.  Until then, drop it.

This commit will regress Piglit's draw-vertices-2101010 test on
pre-Haswell without the corresponding Piglit patch to accept either
formula (commit 35daaa1695ea01eb85bc02f9be9b6ebd1a7113a1):

    draw-vertices-2101010: Accept either SNORM conversion formula.

4dfb8b3416 intel/vs: Grow the param array for clip planes

2975e4c56a intel: Rewrite the world of push/pull params
This moves us away to the array of pointers model and onto a model where
each param is represented by a generic uint32_t handle.  We reserve 2^16
of these handles for builtins that get generated by somewhere inside the
compiler and have well-defined meanings.  Generic params have handles
whose meanings are defined by the driver.

The primary downside to this new approach is that it moves a little bit
of the work that we would normally do at compile time to draw time.  On
my laptop this hurts OglBatch6 by no more than 1% and doesn't seem to
have any measurable affect on OglBatch7.  So, while this may come back
to bite us, it doesn't look too bad.

0d5f89cdc3 i965/vec4: Use NIR remapping for VS attributes
The NIR pass already handles remapping system values to attributes for
us so we delete the system value code as part of the conversion.

We also change nir_lower_vs_inputs to take an explicit inputs_read
bitmask and pass in the inputs_read from prog_data instead from pulling
it out of NIR.  This is because the version in prog_data may get
EDGEFLAG added to it on some old platforms.

700bebb958 i965: Move the back-end compiler to src/intel/compiler
Mostly a dummy git mv with a couple of noticable parts:
 - With the earlier header cleanups, nothing in src/intel depends
files from src/mesa/drivers/dri/i965/
 - Both Autoconf and Android builds are addressed. Thanks to Mauro and
Tapani for the fixups in the latter
 - brw_util.[ch] is not really compiler specific, so it's moved to i965.

v2:
 - move brw_eu_defines.h instead of brw_defines.h
 - remove no-longer applicable includes
 - add missing vulkan/ prefix in the Android build (thanks Tapani)

v3:
 - don't list brw_defines.h in src/intel/Makefile.sources (Jason)
 - rebase on top of the oa patches
