This feature controls the `-Xfrontend -internalize-at-link` flag, which allows the linker to hide public symbols that are not being used and thus dead-strip them. Users of frameworks will need to explicitly export them with an `-exported_symbols_list` if they are not already. PiperOrigin-RevId: 524870535 (cherry picked from commit e8838f2) Signed-off-by: Brentley Jones <github@brentleyjones.com>
