[compiler-rt] [TySan] Added a 'print_stacktrace' flag for more detailed errors (PR #121756)

[via llvm-commits]

Does Tysan support passing options through environment variables, such as TYSAN_OPTIONS? If so, it might be helpful to add a test to check if print_stacktrace works as intended. This could be done using a lit substitution variable like %env_tysan_opts (if not already present?).
