Ideally we would have a VKD3D_SM4_FLAGS_TEXTURE_DIM_SHIFT define or something instead of a plain 2 here.

I'm curious, will this (or, rather, texture loads) work even without some form of copy propagation?
FWIW, this patch breaks register allocation for textures. Basically, has_resource_access never gets set for the "actual" extern variables.

Not as such, but I have a follow-up patch to skip generating synthetic temps if they aren't *actually* assigned to (or, in the case of output variables, read from).
But we should really implement copyprop anyway.

The reservation lookup seems... suboptimal. It's not new (it's basically the same as what we do for buffers already) and probably there won't be that many extern variables in the usual cases, so maybe this is not going to be an issue in practice. It does kind of raise a red flag for me though... I guess let's keep this in mind if we ever happen to encounter performance issues.

I don't like how similar it looks to buffers (and samplers and UAVs), but it's not clear to me how to deduplicate it while not being horribly structured.
I certainly haven't seen shaders with a ton of externs yet.
