Update parser whitespace for clarity (#8539) 
* Update parser whitespace for clarity

Has the nice benefit of not requiring a charCode to String conversion.

* Remove test262 exceptions

Per https://github.com/tc39/ecma262/pull/1218#issuecomment-395340891,
ECMA262 follows whatever the latest Unicode version specifies for Zs

Other_Format category in Unicode 8.
