Render shields before highlighting code

Browse source 
Summary:
It saves some time on non-highlighting generated and other not interesting code.

The code is quite complex (300 lines methods) so I'm not sure if everything is moved correctly.

P.S. I hope that moved code detector will work...

Test Plan:
Display generated file with all whitespace, verify that it is not highlighted.
Display normal file.
