ea83fd9124 glsl: drop NMS OpenGL workarounds
No Mans Sky dropped its OpenGL backend on April 16, 2019 in favour
of its Vulkan backend. So here we drop the old OpenGL workarounds.

a09717c4de glsl: add extra pp tokens workaround and enable for CoR
The CTS now tests to make sure these are not allowed. However, previously
drivers (including Mesa) would allow them to exist and just issue a
warning. Some old applications such as Champions of Regnum seem to
depend on this.

5de56937a3 disk_cache: build option for disabled-by-default
On some systems it is problematic to have the shader cache enabled
by default. This adds a build option to support the disk cache but
keep it disabled unless the environment variable
MESA_GLSL_CACHE_DISABLE=false.

For example, on Chrome OS, Chrome already has it's own shader
disk cache implementation so it disables the mesa feature. Tests
do not want the shader disk cache enabled because it can cause
inconsistent performance results and the default 1GB for the
disk cache could lead to problems that require more effort to
work around. The Mesa shader disk cache is useful for VMs though,
where it is easy to configure the feature with environment
variables. With the current version of Mesa, Chrome OS would need
to have a system-wide environment variable to disable the disk
cache everywhere except where needed. More elegant to just build
Mesa with the cache feature disabled by default.

038fcbcaed glsl: don't duplicate state vars as uniforms in the NIR linker
The linker was adding all state vars as uniforms, doubling the storage size
for shaders using only builtin uniforms, which increased CPU overhead for
constant buffer uploads.

When this code was originally ported from the GLSL IR linker we forgot
to exclude builtins because the check was not done in the
add_uniform_to_shader class but rather a check was done when passing
variables to this class for processing.

assumes the load is aligned just to the size of a scalar value in it.

1ccd681109 nir: Add an LOD parameter to image_*_size
The OpenCL image_width/height/depth functions have variants which can
take an LOD parameter.  More importantly, LLVM-SPIRV-Translator always
generates OpImageQuerySizeLod even if the LOD is guaranteed to be zero.
Given that over half the hardware out there has an LOD field for image
size queries (based on a rudimentary scan through their NIR -> whatever
code), we may as well just add the source to the NIR intrinsic.  If this
is ever a problem for anyone, the lowering is pretty trivial.

I've also added asserts to everyone's drivers that should alert them if
they ever see an LOD other than zero.  This will never happen with GL or
Vulkan so there's no need for panic.

92f5e94a93 glsl: improve precision determination for calls
Don't leave the precision as NONE for non-lowerable calls. Set it to HIGH
if a function really returns highp.

282a1e6288 glsl: don't lower to mediump for desktop OpenGL
Desktop OpenGL ignores all precision qualifiers.

Also, the lowering pass doesn't work if precision qualifiers are not set,
which is only possible with desktop OpenGL, causing random behavior.

0a763c0c86 glsl/lower_precision: split out const lowering
Some hw can narrow 32b const/uniform to 16b on load.. and in particular
lowering constants to 16b would break const->uniform lowering.  Allow
them to lower temps to 16b, while skipping consts.

Initially it is set to the same value as LowerPrecisionTemporaries, to
preserve the current behavior.
