This CL replaces most usages of `.from` (e.g. `List<String>.from(variable)`) to use `.of` instead. This is done because code like `List<String> foo = new List<String>.from([null])` is valid and gives no warnings or errors. Using `.of` instead will give an error. Also `.of` appears to be slightly faster.
