gallium/tgsi_to_nir: Set nir_intrinsic_align_mul to 16 and offset to 0

Since the alignment is now checked in the validator we must set it.

v2: Use alignement of 4, i.e. dest bit size by eight.
v3: Use alignment 16 (Rhys Perry & Jason Ekstand)
v4: Use nir_intrinsic_set_align to make it clear that align offset is 0

    nir: Assert memory loads are aligned
