tgsi_to_nir: Fix the TGSI ARR translation by converting the result to int.
According to the TGSI spec, ARR needs to do a rounding and then
a float-to-integer conversion which was missing. This patch also
makes the rounding a bit more efficient by using nir_fround_even
instead of the previous nir_ffloor+nir_fadd trick.
