Haojian Wu 9f36c7e704 [Tooling] Optimize memory usage in InMemoryToolResults. 
Avoid storing duplicated "std::string"s.

clangd's global-symbol-builder takes 20+GB memory running across LLVM
repository. With this patch, the used memory is ~10GB (running on 48
threads, most of meory are AST-related).

Eric Liu 6828ee3c1d [Tooling] Don't deduplicate tool results in the All-TUs executor. 
Summary:
As result deduplication or reduction is not supported in the framework,
we should leave the deplication to tools (if needed) until the framework supports it.
