Our LLVM sample intrinsics don't preserve the texture target
information. It would be possible to do that with hacks, but I'd
rather avoid that, because it would need a new LLVM IR pass in
radeonsi. The information about level=0 also can't be extracted from
TGSI directly, because it can't enumerate all "defs" of a src operand.
