Merges left.source and right.source into a common source, providing source through that common source to the unknown targets X and Y.
Merges left.source and right.source into a common source, providing source through that common source to the unknown targets X and Y.
In general, if left.source and right.source are equal, we cannot simply return SrcMerge(a1, fm1, fm2) because the Hole in fm1 and fm2 reference some unknown source and do not reference left.source. In this case, our source merging has converged (at least for this iteration), but fm1 and fm2 still reference the old common source (which is not known to us here).
