Auto merge of #9405 - pcwalton:absolute-positioning-overflow, r=glennw

layout: Remove some bogus code that tried to handle absolutely-positioned flows separately when storing overflow.

This code dates back to the time when absolutely positioned flows were
ignored by all of their ancestors up to the containing block. This
hasn't been true for at least a year.

Closes #9306.
Closes #9309.
Is a partial fix for #9308.

r? @glennw
