  -----------
  [Analysis] Teach ScalarEvolution::getRangeRef about more dereferenceable objects (#104778)

Whilst dealing with review comments on

https://github.com/llvm/llvm-project/pull/96752

I discovered that SCEV does not know about the dereferenceable attribute
on function arguments so I have updated getRangeRef to make use of it
by calling getPointerDereferenceableBytes.
