Reviewed by Antti Koivisto.
Source/WebCore:
Remove the iOS-specific #ifdef around code that triggers a compositing re-evaluation
when scrolling state changes.
Test: compositing/scrolling/async-overflow-scrolling/become-non-scrollable.html
* rendering/RenderLayer.cpp:
(WebCore::RenderLayer::updateScrollInfoAfterLayout):
LayoutTests:
Put in a compositing/scrolling/async-overflow-scrolling dir so we can enable it only
for platforms that have async overflow scrolling.
* TestExpectations:
* compositing/scrolling/async-overflow-scrolling/become-non-scrollable-expected.txt: Added.
