nir: add a bit_size parameter to nir_ssa_dest_init

v2: Squash multiple commits addressing the new parameter in different
    files so we don't break the build (Iago)

v3: Fix tgsi (Samuel)

v4: Fix nir_clone.c (Samuel)

v5: Fix vc4 and freedreno (Iago)

v6 (Sam)
- Fix build errors in nir_lower_indirect_derefs
- Use helper to get type size from nir_alu_type.
