because the hw and LLVM only support subdword single-component SSBO loads,
and ac_nir_to_llvm splits multi-component loads because of that, which is
inefficient.

This fixes broken subdword UBO loads with LLVM.
It's only needed for LLVM, but it's done for both LLVM and ACO because
the pass can be fully validated only with ACO and the Vulkan CTS right now.

The pass can't handle it just like the other unpack opcodes and generates
invalid NIR.

This probably doesn't affect Vulkan or GL because they can't have
anything bigger than a vec4 anyway unless it's a u64vec4 and those have
to be at least 8B aligned. This may affect CL apps if they use
__attribute__((packed)) on something with big vectors, depending on how
LLVM decides to translate that.

This should make things more clear than changing the value from earlier
in the loop. Also, rename chunk_offset to load_offset so they match.

Checking against align_mul is insufficient if align_offset > 0. We need
to check against the combined alignment instead.

Indeed, "resolve" is not freed at the gl_framebuffer destroy

For instance, this issue is triggered and detected with
"piglit/bin/fbo-depthstencil clear default_fb -samples=2 -auto"
while setting GALLIUM_REFCNT_LOG=refcnt.log.

Instead of having ac_set_reg_cu_en that sets the register, replace it with
ac_apply_cu_en that only returns the modified register value,
which allows a large simplification in both drivers because a lot of code
becomes duplicated after it's switched to ac_apply_cu_en.
RADV also didn't apply it to a few registers. Fixed.
This removes 82 lines of code in total.

We expect to forward GPU fault information to userspace. Since Mesa can
get that information, we can look up the fault address to log what was
the containing or nearest BO. Add a helper for that, so it can be called
from the driver.
