[Clang] Change two placeholders from `undef` to `poison` [NFC] (#119141)
- Use `poison` instead of `undef` as a phi operand for an unreachable path (the predecessor
will not go the BB that uses the value of the phi).
- Call `@llvm.vector.insert` with a `poison` subvec when performing a
`bitcast` from a fixed vector to a scalable vector.
