  -----------
  Fix for a clang-repl crash when passing non-existent file to --Xcc (#225861)

Problem: When clang-repl fails to initialize because an --Xcc file does
not exist, Interpreter::create() destroys the partially initialized
Interpreter. Its destructor unconditionally calls FinalizeAction(),
which invokes FrontendAction::EndSourceFile() without a registered
CompilerInstance and triggers an assertion.
Fix: Track whether interpreter initialization completed successfully and
only finalize the frontend action for successfully initialized
interpreters.
Test: Add a regression test covering a nonexistent --Xcc file.
