GFX6 doesn't have V_TRUNC_F64, it needs to be lowered. Loosely based
on the AMDGPU LLVM backend.
Introduce a new function because it will be useful for some other
64-bit operations.

Only GFX6 was affected, my mistake. The total number of SGPR operands
should be 4 when we want to create a vec4.

When possible, get rid of an s_not when all it does is invert the SCC,
and its successor s_cbranch / s_cselect can be inverted instead.
Also modify some parts of instruction_selection to take advantage of
this feature.
Example:
s2: %3900, s1: %3899:scc = s_andn2_b64 %0:exec, %406
s2: %3902 = s_cselect_b64 -1, 0, %3900:scc
s2: %407, s1: %3903:scc = s_not_b64 %3902
s2: %3906, s1: %3905:scc = s_and_b64 %407, %0:exec
p_cbranch_z %3905:scc
Can now be optimized to:
s2: %3900, s1: %3899:scc = s_andn2_b64 %0:exec, %406
p_cbranch_nz %3900:scc

By adding an extra instruction, we can replace the operands of
the s_cselect_b64, which allows it to get picked up by the
optimizer when it looks for uniform booleans.

Right now, it's implemented as a no-op for everyone. For most drivers,
it's a switch case in the NIR -> whatever which just breaks. For ir3,
they already have code to delete tessellation barriers so we just add a
case to also delete memory_barrier_tcs_patch.

dEQP-VK.image.image_size.buffer.* was also run with the tests modified to

as opposed to s2 (an SGPR-pair) in wave64 mode.
A couple of cases where this should have been fixed were omitted from
