This is only changing the names that appear in the JS source and should not change the runtime semantics. Prepends "_N_" and "_L_" to nullable and legacy type names. Function types get their markers prepended to the word "To". For example a type `int Function(String)` in a legacy library would have a name in JS like "_L_String_L_To_L_int".
