  Log Message:
  -----------
  [mlir][MemRef] Changed AssumeAlignment into a Pure ViewLikeOp (#139521)

Made AssumeAlignment a ViewLikeOp that returns a new SSA memref equal
to its memref argument and made it have Pure trait. This
gives it a defined memory effect that matches what it does in practice
and makes it behave nicely with optimizations which won't get rid of it
unless its result isn't being used.
