Message:

Move setting of some layout bits to RenderElement
​https://bugs.webkit.org/show_bug.cgi?id=122256

Reviewed by Andreas Kling.

These bits never apply to RenderText nodes:

normalChildNeedsLayout
posChildNeedsLayout
needsSimplifiedNormalFlowLayout
normalChildNeedsLayout
positionedMovementLayout

The code for setting them can be moved to RenderElement.

Also separated the code paths for setting and clearing the bits and uninlined
everything that is not massively popular.
