freedreno/ir3/ra: assign vreg names to all array elements
We shouldn't divide-by-two for half-reg arrays. We set the proper node interference class, based on `arr->half`. Fixes a RA fail with 16b arrays: src/freedreno/ir3/ir3_ra.c:633: name_to_array: Assertion `!"invalid array name"' failed. Caused by use/def iterators returning `arr->length` vreg namess, but only assigning the array half that many names. Also, since we are assigning unique vreg names to each array element, there is no need to try and convert from half-reg to it's conflicting full reg when pre-coloring the array elements. Getting us closer to having half-arrays work sanely with split-register-file (a5xx and earlier).
