  [mlir] Retain metadata for single loc fusedloc

If a fusedloc is created with a single location then no fusedloc
was previously created and single location returned instead. In the case
where there is a metadata associated with the location this results in
discarding the metadata. Instead only canonicalize where there is no
loss of information.
