These decorations allow you to override the signedness of image
instructions. This means that we have to override the type we get from
the sampled image.
Apparently both Intel and AMD get the type from the descriptor rather
than the instruction, but this appears to not be the case with Adreno,
which is why this wasn't noticed until now. So this probably won't fix
any preexisting bugs, but it's required to fix

OpenGL GLSL, OpenGL ARB assembly shaders, and DX9 are pretty loose about
the behavior in the presence of NaNs. Many GPUs that implement these
specifications do not even have a representation of NaN. However,
OpenCL and Vulkan SPIR-V are not so lax. Both actually have some
required behavior in the presence of NaN, and, of the two, OpenCL is the
most strict.
For years we have implemented SPIR-V by using the same comparison
opcodes as we use for OpenGL GLSL and OpenGL assembly shaders. This has
repeatedly caused problems where an optimization that is valid in the
NaN-relaxed world is not valid in Vulkan or OpenCL. To fix this, set
the "exact" flag on comparisons instructions generated from SPIR-V.
This will block optimizations that may have different NaN behavior.
v2: Set the exact flag in the nir_builder, not in the vtn_builder.
v3: Add an assertion in vtn_handle_constant that the exact flag wasn't
set (because it's ignored). Rebase on 80163bbec3 ("nir/vtn: Support
OpOrdered and OpUnordered opcodes"). Mark the NIR generated for those
opcodes as exact as well.
v4: s/unused_exact/exact/ in a couple places, and assert that exact has
the expected value (true in one place, false in the other). Suggested
by Caio.

SPIR-V modules can have multiple shaders (including of the same
stage), but the global variables are all declared for the whole
module. This can result in variables with same Binding but
incompatible types, so those need to be removed before we use.
Previously, a similar issue but with a narrower scope was fixed by
6775665e5e ("spirv: Eliminate dead input/output variables after
translation.").
This patch depends on the previous patch that prevents variables used
only in pointer initializers to be considered dead.
