A future commit will make VCC register assignment independent
from register hints. Up to GFX9, VCC can alternatively be used
as regular SGPR, so prevent overlap.

391bf3ea30 aco: don't expand smem/mubuf global loads 
For example, dwordx3->dwordx4 or ubyte3->dwordx2.

Global loads don't have the bounds checking that buffer loads have that
makes this safe.

The alignment checks are added to global_load_callback() in case
byte_align_loads=false, align=1 and bytes_needed=3. Without them, the
callback will create a dword load.

Designated initializers are a C++20 feature, but we don't use C++20. In
fact, enabling C++20 for ACO triggers new compiler errors due to some
equality semantics details.

So let's instead stop using designated initializers here.

Most regressions seem to be because ACO's convert_pointer_to_64_bit()
can't be CSE'd with radv_nir_apply_pipeline_layout()'s
convert_pointer_to_64_bit(). This should be improved by later commits.

shader.
