Douglas Gregor 057df20b31 Optimize unqualified/global name lookup in modules by introducing a 
generational scheme for identifiers that avoids searching the hash
tables of a given module more than once for a given
identifier. Previously, loading any new module invalidated all of the
previous lookup results for all identifiers, causing us to perform the
lookups repeatedly.

Douglas Gregor 1a4761edca Promote ModuleMap::Module to a namespace-scope class in the Basic 
library, since modules cut across all of the libraries. Rename
serialization::Module to serialization::ModuleFile to side-step the
annoying naming conflict. Prune a bunch of ModuleMap.h includes that
are no longer needed (most files only needed the Module type).

Douglas Gregor 2492c89882 Add support for viewing the module graph via Graphviz, for debugging 
purposes.

Douglas Gregor 98339b96a8 Factor the Module and ModuleManager classes out into separate headers 
and .cpp files, since ASTReader.cpp was getting way too large. No
functionality change.
