[PATCH] D83779: [SLP] Fix order of `insertelement`/`insertvalue` seed operands

This patch takes the indices operands of `insertelement`/`insertvalue`
into account while generation of seed elements for `findBuildAggregate()`.
This function has kept the original order of `insert`s before.
Also this patch optimizes `findBuildAggregate()` preventing it from
redundant temporary vector allocations and its multiple reversing.

Fixes llvm.org/pr44067
