We don't properly pass on ctx.lgkm_cnt/ctx.barrier_imm/etc, so this
waitcnt was necessary for barriers and correctly waiting for SMEM before
s_dcache_wb on GFX10.

4c060235a2 freedreno/ir3: handle scalarized varying inputs
If the load_interpolated_input is scalarized, we would be too
conservative about deciding the tex instruction wasn't a candidate to
pre-fetch:

	vec1 32 ssa_0 = load_const (0x00000000 /* 0.000000 */)
	vec2 32 ssa_1 = intrinsic load_barycentric_pixel () (0) /* interp_mode=0 */
	vec1 32 ssa_2 = intrinsic load_interpolated_input (ssa_1, ssa_0) (0, 0) /* base=0 */ /* component=0 */	/* packed:v_uv,v_uv1 */
	vec1 32 ssa_3 = intrinsic load_interpolated_input (ssa_1, ssa_0) (0, 1) /* base=0 */ /* component=1 */	/* packed:v_uv,v_uv1 */
	vec2 32 ssa_8 = vec2 ssa_2, ssa_3
	vec4 32 ssa_9 = tex ssa_8 (coord), 0 (texture), 0 (sampler)

Really we don't care that the texcoord components come from different
load_interpolated_input instructions, just that they have consecutive
varying offsets.

a13320370e radv: fix updating bound fast ds clear values with different aspects
On GFX9, the driver is able to do an optimized fast depth/stencil
clear with only one aspect (ie. clear the stencil part of a
depth/stencil image). When this happens, the driver should only
update the clear values of the given aspect.

Note that it's currently only supported on GFX9 but I have some
local patches that extend this optimized path for other gens.

1749953ea3 aco/gfx10: Wait for pending SMEM stores before loads
Currently if you have an SMEM store followed by an SMEM load that
loads the same location as was written, it won't work because the
store isn't finished before the load is executed. This is NOT
mitigated by an s_nop instruction on GFX10.

Since we currently don't have proper alias analysis, this commit adds
a workaround which will insert an s_waitcnt lgkmcnt(0) before each
SSBO load if they follow a store. We should further refine this in
the future when we can make sure to only add the wait when we load the
same thing as has been stored.

7fa5cd3ee3 panfrost: Fix the DISCARD_WHOLE_RES case in transfer_map()
The current implementation does not synchronize on BO readiness when
DISCARD_WHOLE_RES flag is set, which can lead to misbehaviours when the
resource being updated is being used by one of the pending or already
flushed batches.

Adding unconditional BO synchronization would do the trick, but we can
sometimes optimize this path by re-allocating a new BO instead of
waiting for the existing one to be ready.
