Taken mostly directly from the anv pass. A few anv-specific things that
I could leave in anv aren't included. Specifically on turnip we don't
need to set gl_Layer to 0, and we can handle the case where the FS reads
gl_ViewIndex, so that check is moved into anv.

We might have several identical options to vectorize an entry with, but
only one might be vectorizable because of writes interfering.
An example of this is a pattern found in some CTS tests:
a = load(0)
b = load(4)
store(0, a)
store(4, b)
a = load(0)
b = load(4)
store(0, a)
store(4, b)
...
It might have attempted to vectorize the first load(0) with the second
load(4) without attempting the second load(4) when the first fails. This
changes vectorize_entries() to continue even if the first try_vectorize()
failed.

Section 5.11 (Out-of-Bounds Accesses) of the GLSL 4.60 spec says:
"In the subsections described above for array, vector, matrix and
structure accesses, any out-of-bounds access produced undefined
behavior.... Out-of-bounds reads return undefined values, which
include values from other variables of the active program or zero."
Robustness extensions suggest to return zero on out-of-bounds
accesses, however it's not applicable to the arrays of samplers,
so just clamp the index.
Otherwise instr->sampler_index or instr->texture_index would be out
of bounds, and they are used as an index to arrays of driver state.

GL_KHR_robustness and GL_ARB_robustness encourage us to return zero
for reads.
Otherwise get_io_offset would return out-of-bound offset which may
result in out-of-bound loading/storing of inputs/outputs,
that could cause issues in drivers down the line.

In CL 1.2, images are required to be either read-only or write-only. We
can always translate the read-only image ops to texture ops. In CL 2.0
(and an extension), the ability is added to have read-write images but
sampling (with a sampler) is only allowed on read-only images. As long
as we only lower read-only images to texture ops, everything should stay
consistent.

In SPIR-V, the access qualifiers for an image are provided on the image
type. Assuming no one swaps the types around on us (I think that should
be illegal), this means we can reliably fetch the access qualifiers from
the type itself. The ops which don't really have an easy-to-fetch type
are the atomics because they use OpImageTexelPointer. However, those
are only allowed on read/write images and that's the default.
