[clang] Fix some static initialization race-conditions (#181367) - clang/StaticAnalyzer: fix static init in findKnownClass. Prior to this patch two threads running in findKnownClass could result in a race condition. - clang/Stmt: fix StmtClassNameTable array initialization: prior to this patch there was a race condition when two threads check`if(Initialized)` at the same time. - clang/ParsedAttrInfo: fix race condition in getAttributePluginInstances. Prior to this patch two threads could enter `if(empty())` check. - clang/CodeGen: correctly restore diagnostic handler in HandleTranslationUnit. Prior to this patch an early exit from HandleTranslationUnit could result in not restoring previous diagnostic handler.
