17c779ab9e aco: Skip 2nd read of merged wave info when TCS in/out vertices are equal.
When TCS has an equal number of input and output, it means that the
number of VS and TCS invocations (LS and HS) are the same; and that
the HS invocations operate on the same vertices as the LS.

When this is the case, this commit removes the else-if between
the merged VS and TCS halves, making it possible to schedule
and optimize the code accross the two halves.

4ec48440a0 aco: Allow combining LDS loads when loading tess factors.
Previously the tess factors were loaded individually, but now they can
be loaded using a single LDS load instruction.

Note that the inner and outer tess factors are not yet combined.

43918c9a7f aco: implement 64-bit VGPR constant copies in handle_operands()
64-bit VGPR constant copies can happen because of 64-bit constant copy
propagation. Since this optimization is beneficial and more annoying to
deal with in the optimizer, I've implemented 64-bit VGPR constant copies
in handle_operands().

This also sets copy_operation::size correctly for 64-bit constant copies.

56de6f698e radv: remove wrong assert that checks compute subgroup size
Ooops. For some reasons, I have been confused with Wave32 on GFX10,
but it's still possible to require a specific subgroup size if
only Wave64 is supported.

46e8ba1344 radv: only inject implicit subpass dependencies if necessary
The Vulkan 1.2.134 spec update clarified when implicit subpass
dependencies should be injected by the driver. They only make
sense if automatic layout transitions are performed.

This should fix a performance regression with RPCS3 (although
they added a workaround for RADV since the regression has been found).

ee9e0d1eca aco: set late kill for v_interp_p1_f32 for some APUs
Apparently needed for Stoney Ridge, Kabini and Mullins APUs.

gfx702 also has 16-bank LDS and https://llvm.org/docs/AMDGPUUsage.html
lists some dGPUs under there. Those GPUs seem to be Hawaii actually
(gfx701) and we don't seem to have gotten any interpolation related bugs
reported with them so far.

The late kill flag was tested by running pipeline-db with
ACO_DEBUG=validatera while setting late kill for SMEM buffer loads,
emit_vop2_instruction() and texture instructions. I also tested with
just setting the flag for v_interp_p1_f32.

As far as I know, the only other thing we have to consider for 16-bank LDS
is something to do with 16-bit interpolation. We don't do that yet.
