nir_to_tgsi: Use ARL instead of UARL in the !native_integers case.

Browse source 
Our "integer" index is stored as a float in this case, and we just need to
use teh right opcode for loading it, which will be the only one supported
by !native_integers hardware.

Fixes: cf3fc79cd0 ("st/mesa: Replace mesa_to_tgsi() with prog_to_nir() and nir_to_tgsi().")
