976b0065 - [RISCV] Disable combineToVCPOP for illegal scalable vector types. (#140195)

[RISCV] Disable combineToVCPOP for illegal scalable vector types. (#140195) This transform creates target specific instructions which must have legal types. We were checking this for fixed vectors, but not scalable vectors. This caused a crash with <vscale x 1 x i1> which isn't legal for Zve32x.
