crisbeto 664e0015d4 perf(ivy): replace select instruction with advance (#32516)
Replaces the `select` instruction with a new one called `advance`. Instead of the jumping to a specific index, the new instruction goes forward X amount of elements. The advantage of doing this is that it should generate code the compresses better.
