It's legal in SPIRV for functions to not have names, we have to take this

I noticed some unnecessary 64-bit ints in shaders that were using doubles.
Perhaps there's a different missing optimization that should run on the
actual pack/unpack instructions before they're lowered, or maybe I'm just
lowering them too early, but these seem simple enough that we might want
them even for hand-rolled pack/unpack pairs.

fsign's result can be +0.0 or -0.0 for -0.0. We already calculate
the signed zero, it's even faster to replace the fmul(fsign(x), ...) with ior.

The constant-folding definition and comments say that it takes the high
16 bits of the first source and low 16 bits of the second source, but
actually it's the opposite. The algebraic optimization, which actually
happens and needs to be correct, was correct but the comment above it
was wrong.
Note that in the way we use it when lowering multiplications, the
ordering doesn't matter.

With float_controls2, shaders can decide on the behavior of
NaN/Inf/SignedZero preservation by decorating specific instructions, on
top of having a default for the whole program.
Add where to track these to nir_alu_instr and propagate them to new
instructions everywhere that exact is being done already.

Some uses don't have any post-dominator. An example is an atomic that
feeds itself in a loop. No instruction immediately post-dominates
the result of such an atomic because no instruction can strictly
post-dominate itself. This handles that case generally by setting
the root node as the post-dominator for instructions that can't be
reordered.
