Auto merge of #77229 - tmiasko:liveness, r=lcnr

Small improvements in liveness pass * Remove redundant debug logging (`add_variable` already contains logging). * Remove redundant fields for a number of live nodes and variables. * Delay conversion from a symbol to a string until linting. * Inline contents of specials struct. * Remove unnecessary local variable exit_ln. * Use newtype_index for Variable and LiveNode. * Access live nodes directly through self.lnks[ln]. No functional changes intended (except those related to the logging).
