9bb376bbdb pan/bi: Use the correct size for UBO loads
Multiply by the destination bit size to get the number of bits to
load instead of assuming 32 bits.

93824b6451 panfrost: Move the blend logic out of the gallium driver
Most of it is API-independent, so let's move it out of the gallium
driver so it can be shared with the Vulkan driver.

d5b1a33460 panfrost: Move the shader compilation logic out of the gallium driver
While at it, rework the code to avoid copies between intermediate
structures: the pan_shader_info is passed to the compiler context so
the compiler can fill shader information directly.

fa79168b9e pan/bi: Simplify derivative lowering
Now that we lower FAU correctly, we don't need to write the extra move
explicitly, it will be lowered in later.

0acc6b564e pan/bi: Rework FAU lowering
Move and reshape bi_lower_fau to bi_schedule.c. This generalizes the
pass for FAU reads, allowing copyprop to work with FAU without problems.

The pass must run immediately before scheduling. Its post-conditions are
directly specified as the scheduler's pre-conditions. It momentarily
will depend on internal scheduler predicates. It is, for all intents and
purposes, part of the scheduler. Keep it all together.

Finally, adjust the 0 handling to avoid a move at the expense of
constrained scheduling of something like `FADD.v2f16.clamp_0_1 u0, #0`
