i965/fs: Use byte_scattered_write on 16-bit store_ssbo
We need to rely on byte scattered writes as untyped writes are 32-bit size. We could try to keep using 32-bit messages when we have two or four 16-bit elements, but for simplicity sake, we use the same message for any component number. We revisit this aproach in the follwing patches. v2: Removed use of stride = 2 on 16-bit sources (Jason Ekstrand) v3: (Jason Ekstrand) - Include bit_size to scattered write message and remove namespace - specific for scattered messages. - Move comment to proper place. - Squashed with i965/fs: Adjust type_size/type_slots on store_ssbo. (Jose Maria Casanova) - Take into account that get_nir_src returns now WORD types for 16-bit sources instead of DWORD. v4: (Jason Ekstrand) - Rename lenght variable to num_components. - Include assertions before emit_untyped_write. - Remove type_slot in favor of num_slot and first_slot.
