Most of this is fairly straightforward; we just set all the modes on any
derefs which are generic. The one tricky bit is OpGenericCastToPtrExplicit.
Instead of adding NIR intrinsics to do the cast, we add NIR intrinsics
to do a storage class check and then bcsel based on that.

This will create code that is easier to combine into MADs/FMA when the
last component of the vector is 1.0.
nir_opt_algebraic_late has an optimization to do something similar but it
only works for inexact code, if the multiplication-by-1 optimization is
done before it and if the backend enables fuse_ffma.

We're about to introduce conversion ops which are going to want two

end up with three. There are a couple places where this is mildly
inconvenient but most of the time I find it to actually be nicer.

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.

SPIR-V's OpKill is a control-flow instruction but NIR's discard is not.
Therefore, it can be valid SPIR-V to have
if (...) {
foo = /* something */
} else {
discard;
}
use(foo);
without any phi between the definition of foo and its use. This is not
true in NIR, however, because NIR's discard isn't considered
control-flow. Arguably, this is a NIR bug but making discard control-
flow is a very deep change that can have serious ans subtle
side-effects. The easier thing to do is just fix up the SSA in case we
have an OpKill which might have gotten us into the above case.
Fixes dEQP-VK.graphicsfuzz.vectors-and-discard-in-function with the new
