nvir: introduce OP_SHF
We already use a hack from NVC0LegalizeSSA::handleShift() on GK110 and
newer which encodes SHF into the existing SHL/SHR opcodes, but there's
a couple of problems with it:
- LO/HI are swapped in one of the directions, which is very confusing.
- The initial SM70 code will emit this from NIR->NVIR, and using the
existing encodings will confuse the optimisation passes.
As I want to limit the impact on other GPUs from the initial bring-up
of Volta/Turing, let's add an explicit representation of SHF in the IR.

gallium/hud: do not specify potentially invalid depth-range
Setting the depth-scale to 1 while leaving the depth-translation at 0
means our near-plane is at -1 in OpenGL semantics, which is
out-of-range on some drivers. In particular, Zink has this limitation.
But since we'll only pass a zero z in here anyway, we might as well
multiply it by zero, and get the same result. This avoids the problem.
