9c35a7bf - [AArch64] Refine reduction VT selection in CTPOP -> VECREDUCE combine (#183025)

[AArch64] Refine reduction VT selection in CTPOP -> VECREDUCE combine (#183025) Use the same VT as the SETcc source, or fall back to using the VT of the unextended operand of the CTPOP if the element size of the SETcc is too small to fit the negative popcount.
