4e7a777093 aco: try forming clauses even if reg_pressure exceeds 
This patch allows to form clauses even if the register pressure
is at the limit with the effect that VMEM instructions are less
scattered after the first clause in a Block.
It respects the previous clause size to avoid excessive moving
of VMEM instructions.
VMEM_CLAUSE_MAX_GRAB_DIST is further reduced to compensate
some of the effects.

8341af5109 radv, aco, ac/nir: Tweak position export scheduling for NGG culling. 
The result is about +5-ish fps in Doom Eternal.

It turns out that the location of position exports matters more
than we thought, and it's actually better to keep them at the bottom
for culling shaders rather than schedule it up to the top.

50ba919d37 aco/scheduler: Fix register demand computation for upwards moves 
The initial value needs to be taken from the instruction that is being
moved over, not the one to be moved.

Additionally the parameter of this function was removed because it was
misleading. Setting it to any value other than source_idx would cause
register_demand to be initialized incorrectly. (Instead, the maximum
demand among the covered instructions would need to be determined.)
