Boris Brezillon c97f79ac0c pan/va: Optimize SSBO lowering on Valhall 
For reads, we use the LD_PKA (AKA LD_BUFFER) so we can directly
pass the buffer index. For writes, we still convert the SSBO index
into a global address before doing a global load/store/atomic
operation, but we do that with an LEA_PKA instruction that takes
care of bounds checking.
