Cross-module incremental builds require a stable source of fingerprint information for iterable decl contexts. This is provided by the incremental frontends when they produce partial swift module files. Embedded in these files is a table of fingerprints, which are consumed by merge-modules to construct a module-wide dependency graph that is then serialized into the final merged swift module file. Unfortunately, the implementation here iterated through the files in the module and asked for the first fingerprint that would load for a particular iterable decl context. If (more likely, when) the DeclID for that serialized iterable decl context collided with another DeclID in the wrong file, we would load that fingerprint instead. Locate up to the module-scope context for an iterable decl context and only load the fingerprint from there. This ensures that the fingerprints in the partial modules matches the fingerprints in the merged modules. rdar://77005039
