Yingwei Zheng 18311093ab [InstCombine] Do not fold shufflevector(select) if the select condition is a vector (#113993) ...

Since `shufflevector` is not element-wise, we cannot do fold it into
select when the select condition is a vector.
For shufflevector that doesn't change the length, it doesn't crash, but
it is still a miscompilation: https://alive2.llvm.org/ce/z/s8saCx

Fixes https://github.com/llvm/llvm-project/issues/113986.
