glsl_to_tgsi: use UARL instead of I2F and ARL
Since TGSI now has a UARL opcode that takes an integer as the source, it is no longer necessary to hack around the lack of an integer ARL opcode using I2F. UARL is only emitted when native integers are enabled; ARL is still used otherwise. Reviewed-by: Brian Paul <brianp@vmware.com>
