  • 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).

This seems like it might slightly improve performance, so @bors rollup=never
