4eb4197d27 intel/nir/rt: fix reportIntersection() hitT handling 
We're currently updating the hitT value in the traversal result with
the hitT value from reportIntersection(), but this is not correct.

First the hitT value of reportIntersection() should update the
gl_RayTmaxEXT value (maps to brw_nir_rt_mem_ray_defs::t_far).

Second the hitT determined by traversal should only be updated if the
reportIntersection() hitT value has updated the gl_RayTmaxEXT and that
the new gl_RayTmaxEXT is smaller than the determined hitT value from
traversal.

4695bebc79 nir: Drop nir_dest 
Instead, we replace every use of it with nir_def.  Most of this commit
was generated by sed:

   sed -i -e 's/dest.ssa/def/g' src/**/*.h src/**/*.c src/**/*.cpp

A few manual fixups were required in lima and the nir_legacy code.
