The last 12 bytes are always 0 for now. With this, all SHA1 functions
can be internally implemented as BLAKE3, so that we can switch everything

18b8543026 ac/nir: Add pass to fixup SMEM on GFX6-7 
The pass implements two mitigations for the GFX6-7 SMEM bug:

1. To mitigate VM faults by NULL descriptors:

Make sure that SMEM buffer loads always access a mapped BO.
Use either the descriptor BO (or compute scratch BO),
or otherwise use the zero-filled BO in their place.

2. To mitigate VM faults by OOB robust buffer access:

Add an instruction to clamp the offset source to the
num_records field of the descriptor. It will be still
out of bounds, but the VM fault can be completely mitigated
if the driver adds a padding to each memory allocation.
