Currently the meosn build has a mix of two styles:
arg : [foo, ...
bar],
and
arg : [
foo, ...,
bar,
]
For consistency let's pick one. I've picked the later style, which I
think is more readable, and is more common in the mesa code base.

When a TCS is present at link time we know the number of vertices in the
patch and we can lower gl_PatchVerticesIn in the TesEval stage directly
to a constant. We already have a pass for this that we use in the
Vulkan pipeline, so we just reuse that.
Notice that the GLSL linker also implements this optimization, which
we are not removing because other drivers may still depend on it, so
this should only be useful for OpenGL SPIR-V shaders for now.

Apparently, Geminilake requires you to whack a chicken bit to select
either compute or tessellation mode for barriers. The recommendation
is to switch between them at PIPELINE_SELECT time.
We may not need to do this all the time, but I don't know that it hurts
either. PIPELINE_SELECT is already a pretty giant stall.
This appears to fix hangs in tessellation control shaders with barriers
on Geminilake. Note that this requires a corresponding kernel change,
drm/i915: Whitelist SLICE_COMMON_ECO_CHICKEN1 on Geminilake.
in order for the register write to actually happen. Without an updated
kernel, this register write will be noop'd and the fix will not work.

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):

tl;dr: For many types of GL object, we can *NEVER* use the Gen function.
In OpenGL ES (all versions!) and OpenGL compatibility profile,
applications don't have to call Gen functions. The GL spec is very
clear about how you can mix-and-match generated names and non-generated
names: you can use any name you want for a particular object type until
you call the Gen function for that object type.
Here's the problem scenario:
- Application calls a meta function that generates a name. The first
Gen will probably return 1.
- Application decides to use the same name for an object of the same
type without calling Gen. Many demo programs use names 1, 2, 3,
etc. without calling Gen.
- Application calls the meta function again, and the meta function
replaces the data. The application's data is lost, and the app
fails. Have fun debugging that.
