Mali4x0 has stride only for level 0, so other leves have stride of
width * bpp. That likely means that any level except 0 can't be render
target. We can workaround it by using tiled textures wherever possible
since they're actually aligned to tile boundaries.

NIR may emit a single instrinsic to load several packed varyings,
but that's suboptimal for Utgard PP for several reasons:
- varyings that are used as sampler inputs can be passed using
  pipeline register with increased precision
- we have small number of regs, so using a vec4 regs for storing
  two vec2 varyings increases reg pressure.

Add NIR pass to split a single load into several loads and utilize
it in lima.

According to radeonsi, GLM doesn't support WB alone, so
we have to set INV too when WB is set.

The old version of the iterators relies on a &iter->field != NULL check
which works fine on older GCC but newer GCC versions and clang have
optimizations that break if you do pointer math on a null pointer.  The
correct solution to this is to do the null comparisons before we do any
sort of &iter->field or use rb_node_data to do the reverse operation.

As Vasily discovered, the bit 7 of the word 1 of the texture descriptor
is set when reloading the framebuffer, to use framebuffer-based offset
rather than normalized one. This bit also works for regular textures to
enable accessing with non-normalized offset.

Add support for rectangle texture by setting this bit for
PIPE_TEXTURE_RECT.

Per the valgrind output below, we were returning the pointer to freed
memory if none of the later conditional pointer assignments were
executed. This caused dEQP CI jobs to crash on certain runners,
presumably due to a double-free down the line.

Also, we were skipping to the out: label before the vendor_id & chip_id
variables used by it were initialized, resulting in broken
LIBGL_DEBUG=verbose output such as

libGL: pci id for fd 4: 51108f00:51108f00, driver radeonsi
