[llvm] ADT: Add non-const overload of PackedVector::raw_bits() (PR #101742)

[Nicolai Hähnle via llvm-commits]

https://github.com/nhaehnle created https://github.com/llvm/llvm-project/pull/101742

This is convenient when operating on vectors in a bulk, bit-manipulating fashion. I plan to use this in a future change.
