Ensure that the identifier chains have the most recent declaration after module deserialization.

This commit introduces a set of related changes to ensure that the
declaration that shows up in the identifier chain after deserializing
declarations with a given identifier is, in fact, the most recent
declaration. The primary change involves waiting until after we
deserialize and wire up redeclaration chains before updating the
identifier chains. There is a minor optimization in here to avoid
recursively deserializing names as part of looking to see whether
top-level declarations for a given name exist.

A related change that became suddenly more urgent is to property
record a merged declaration when an entity first declared in the
current translation unit is later deserialized from a module (that had
not been loaded at the time of the original declaration). Since we key
off the canonical declaration (which is parsed, not from an AST file)
for emitted redeclarations, we simply record this as a merged
declaration during AST writing and let the readers merge them.

Reformat lines if they were "moved around".

An unwrapped line can get moved around if there is no newline before
it and the previous line was formatted.

Example:

  template<typename T>  // Cursor is on this line when hitting "format"
  T *getFETokenInfo() const { return static_cast<T*>(FETokenInfo); }

"return .." is the second unwrapped line in this scenario. I does not
touch any reformatted region. Thus, the result of formatting is:

  template <typename T> T *getFETokenInfo() const { return static_cast<T *>(FETokenInfo); }

After second format (and arguably desired end-result):
