- Make let, const, and class symbols be declared in a block scope. - Piggy back on existing catch symbol implementation to get block-aware mangling working - Make sure unused block-scoped declarations can be dropped - Don't eliminate a block if it has a block-scoped declaration - Remove silly empty anonymous blocks left over from drop_unused - AST_Toplevel now gets to call drop_unused too, since block-scoped variables aren't global! - Don't consider block declarations global
