Unnecessary ImplementationLacksVTable IDL attribute used for RTCConfiguration, RTCIceServer
https://bugs.webkit.org/show_bug.cgi?id=130230

Reviewed by Philippe Normand.

The RTCConfiguration and RTCIceServer classes do not own virtual tables, so using the
ImplementationLacksVTable attribute in the IDL interface leads to a compile-time assertion
failure in the generates JSC wrappers because none of the classes is polymorphic.

[CSSRegions] Inline-block child of content node incorrectly clipped
https://bugs.webkit.org/show_bug.cgi?id=130229

Reviewed by Andrei Bucur.

Source/WebCore:

Constrain the target box rect to the region box rect only if we are able
to determine the region range for box. If we cannot do that, getRegionRangeForBox
returns null values for start and end region and we should not perform the clamping.
