[PATCH, rs6000] Merge two vector shift when their sources are the same

Hi, This patch merges two "vsldoi" insns when their sources are the same. Particularly, it is simplified to be one move if the total shift is multiples of 16 bytes. Bootstrapped and tested on powerpc64-linux BE and LE with no regressions. Thanks Gui Haochen ChangeLog 2023-02-20 Haochen Gui
