I had a funny +1 in nir_to_tgsi's load_ubo lowering on the buffer index,
because I hadn't set lower_uniform_to_ubo for softpipe. This removes that
weirdness in favor of just using lower_uniform_to_ubo, regardless of
driver preference (which matters if a NIR-native driver had it set, and
then the gallium draw module triggered the non-LLVM TGSI fallback path
that hit NTT).

GL by default gives you UB when you access a missing constbuf, and we were
crashing on debug builds in that case. More importantly, we were
assertion failing even under valid circumstances, when a !ExecMask channel
had a bad value for the indirect buffer index and we tried to load from it
anyway.
In removing the assertion, also sink the buf declaration to after we've
done the bounds check that determines that there's a constbuf actually
bound to this index.

There's not really a reason to directly map textures. Doing so
requires the texture to be allocated in system RAM instead of
video RAM, which means all GPU access to it would be needlessly slow.
Notably, the one texture type that was allocated this way is the
display target texture for the software driver path. Instead, use
pipe_transfer_map to be able to copy the texture to system RAM.

Currently all buffers are allocated as mappable, but a future
commit will change that so that some buffers can be allocated
directly in non-CPU-accessible memory for improved performance.
Note that the returned pointer must be appropriately offset from
a 64-byte-aligned base pointer, so if offsets are used, the data
will be read/written to an offset region in the staging buffer.

The mantissa for a float doesn't contain enough data to accurately represent
the min/max values for some destination types. Instead of clamping before
converting, clamp after converting when coming from floats. This improves
conformance of CL conversions, specifically for float -> long/ulong with
int64 emulation enabled.
Refactors the limit determination from the clamp, so we can determine
limits for the dest type (int/uint) in both the source (float) and dest
type. The limit as a float is used for comparison, while the limit as a
dest type is used for bcsel.
Important note is that the comparison is inverted to fge instead of flt,
so the bcsel chooses the direct int/uint over the converted float in the
case where the comparison comes up equal, but the conversion can't produce
the exact min/max value.

Some DRI extension features are enabled/disabled
based on capabilities of the gallium pipe_screen
associated with the DRI screen. Additionally, the
list of extensions enabled also varied based on
features requested by the screen creator. However,
prior to this change the extension list and
extension definition structures within it were
global variables, meaning the last screen
initialized ended up defining the DRI capabilities
of all screens.
This change instead stores a copy of the
extensions which vary per screen, as well as a
copy of the extension list itself in the gallium
DRI screen structure, allowing them to vary per
screen.

Quote from the OpenGL Shading Language spec, version 4.40, section 8.9.2
"Texel Lookup Functions":
> The offset value must be a constant expression.
So, until we start consuming SPIR-V shaders, it seems we don't need to
deal with non-constant offsets.
This means we can avoid lowering this away in some cases.
