  Changed paths:
    M clang/lib/Serialization/GlobalModuleIndex.cpp

  Log Message:
  -----------
  Return false if the identifier is not in the global module index.

This allows clients to use the idiom:

if (GlobalIndex->lookupIdentifier(Name, FoundModules)) {
  // work on the FoundModules
}

This is also a minor performance improvent for clang.
