[InstCombine] Recognize more rotation patterns (#78107)

InstCombine already handles the pattern `(shl ShVal, (X & (Width - 1)))
| (lshr ShVal, ((-X) & (Width - 1)))`. Under certain circumstances, `X &
(Width - 1)` will be simplified to `X`. Therefore, this patch adds
support for the pattern `(shl ShVal, X) | (lshr ShVal, ((-X) & (Width -
1)))`.
