1. Better sorting of scalars to be gathered. Trying to insert constants/arguments/instructions-out-of-loop at first and only then the instructions which are inside the loop. It improves hoisting of invariant insertelements instructions. 2. Better detection of shuffle candidates in gathering function. 3. The cost of insertelement for constants is 0. Part of D57059.
