Vinayaka Bandishti a3917d3670 [MLIR][Affine] Privatize certain escaping memrefs ...

During affine loop fusion, create private memrefs for escaping memrefs
too under the conditions that:
-- the source is not removed after fusion, and
-- the destination does not write to the memref.

This creates more fusion opportunities as illustrated in the test case.
