perf: update loop micro optimize

[chiefcll]

Since most nodes are just marked with UpdateType.Children - added a top level

if (updateType > 1) // line#1101

To skip all the other checks.

(rest is just formatting and indent)

I cant review this with all the indent changes, could you leave that as is and only diff the changes you made?

@wouterlucas - I just added this:

if (updateType > UpdateType.Children) { to line 1101. If you want to make the change directly that might be easier as indenting all the code is what causes this diff.
