REGRESSION in position of autocomplete popup on RTL page.

RTL static position computation did not subtract out the width of the enclosing box if the
immediate parent was a RenderInline.  This bug was exposed by properly changing the RenderView
to be RTL when the document was RTL.

Added three new tests in fast/block/positioning.

* rendering/RenderBox.cpp:
(WebCore::RenderBox::computePositionedLogicalWidth):
