ffb9bbfd - [mlir][MemRef] Changed AssumeAlignment into a Pure ViewLikeOp (#139521)

[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.
