locations are important for these because they provide info about how
many block indices each ubo takes up
UBO arrays have nonzero values here. all non-array UBOs have either 0
for the base or nonzero for an io lowered block at an offset,
but only arrays need to be changed here because they're the only ones
with absolute values, whereas all the others are relative.

while linking uniforms, we might get a variable which is the only reference
to the ubo (i.e., offset 0), as determined by its type being the UBO's
interface_type, at which point we can assign the previously-gotten
block index to this variable's location

With arrays we really have to use the correct size for the base
mipmap to get the right array pitch. In particular, using
surf_pitch results in pitch that is bigger than the base mipmap
and hence results in wrong pitches computed by the HW.
It seems that on GFX9 this has mostly been hidden by the epitch
provided in the descriptor but this is not something we do on
GFX10 anymore.
Now this has some draw-backs:
1. normalized coordinates don't work
2. Bounds checking uses slightly bigger bounds.
2 mostly is not an issue as we still ensure that they're within
the texture memory and not overlapping other layers/mips, but
we can't properly ignore writes.
1 is kinda dead in the water ... On the other hand I'd argue that
using normalized coords & a filter for sampling a block view of
a compressed format is extraordinarily useless.
The old method we employed already had these drawbacks for everything
except the base miplevel of the imageview.
AFAICT this is the same tradeoff AMDVLK makes and no CTS test hits
this. (once it does I think the HW is dead in the water ... Only
workaround I can think of is shader processing which is hard because
we don't know texture formats at compile time.)
I also removed the extra calculations when the image has only 1 mip
level because they ended up being a no-op in that case.

nir_lower_io_arrays_to_elements lowers arrays or matrices to elements,
which ends up to vectors for matrices, but a bunch of IO optimizations
only work for scalars.
Calling it before lower_io_to_scalar_early allows nir_link_opt_varyings
to remove duplicated inputs and replace constant inputs.

With us not creating a bo_list anymore, there is a problem if we
delete a buffer between enumerating all buffers and doing the submission.
Also changes this to a rwlock given the wider scope of the things under
lock. (especialy some of the syncobj stuff is now under the lock)

Since 1e7d82c881 ("nir/algebraic: always lower idiv
to shifts if bitops are allowed") idiv is lowered and
generates a isign operation.
VC4 HW doesn't support isign and lower_isign wasn't enabled.
Enabling it fixes the regressions caused by this new
optimization on piglit tests shaders/glsl-fs-loop-nested.
