Carry lookup configuration throughout lookup on the LookupResult. Give
LookupResult RAII powers to diagnose ambiguity in the results. Other diagnostics
(e.g. access control and deprecation) will be moved to automatically trigger
during lookup as part of this same mechanism.
This abstraction makes it much easier to encapsulate aliasing declarations
(e.g. using declarations) inside the lookup system: eventually, lookup will
just produce the aliases in the LookupResult, and the standard access methods
will naturally strip the aliases off.
