Fix stack overflow and improve performance when a module contains many overloads of a name by claiming that there are no lookup results for that name in modules while loading the names from the module. Lookups in deserialization really don't want to find names which they themselves are in the process of introducing. This also has the pleasant side-effect of automatically caching PCH lookups which found no names. The runtime here is still quadratic in the number of overloads, but the constant is lower. llvm-svn: 174685
