The option use_interpolated_input_intrinsics will lower these as well

produce optimal code for regular input loads based on the input
variable layout qualifiers, so this change adds an option to only
lower instances of interpolateAt().

Alejandro Piñeiro 10b79bf901 nir: include texture query lod as one of the ops that requires a sampler 
In practice we found that we need this for v3d (specifically for cube
map arrays, as they don't support the default value for wrap_i, so a
sampler object is needed to override that value).

It is worth to note that the main reason behind this auxiliar method
was to identify those cases that we didn't have a sampler object
available for Vulkan. So far, we found that we have a sampler object
coming from nir always for that operation.

Fixes cube map array tests like the following:

John Bates 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.

Marek Olšák 1e7d82c881 nir/algebraic: always lower idiv to shifts if bitops are allowed
