  [SLP] Propagate through instrinsics in BoUpSLP::getVectorElementSize() (#199129)

We propagate through simple binary operations already, some operations
are excluded since it happens to be an intrinsic.

Motivated by case exposed when removing vectorization from pre-LTO, see
https://github.com/llvm/llvm-project/pull/195886#issuecomment-4486422243.
