(WebCore::RenderBox::constrainLogicalWidthInRegionByMinMax):
(WebCore::RenderBox::computeLogicalWidthInRegion):
(WebCore::RenderBox::computeLogicalWidthInRegionUsing):
Pass in the Length so that RenderFlexibleBox can call this method and avoid
doing a bunch of code duplication.

* rendering/RenderBox.h:
* rendering/RenderFlexibleBox.cpp:
(WebCore::RenderFlexibleBox::computeMainAxisExtentForChild):
Instead of just calling valueForLength, call computeLogicalWidthInRegionUsing so that
we properly resolve intrinsic Length types. Incidentally, this should also make viewport
percentage units work.

(WebCore::RenderFlexibleBox::adjustChildSizeForMinAndMax):
Resolve intrinsic min/max Lengths. Also, instead of calling minPreferredLogicalWidth for the
min-width: auto case, call computeMainAxisExtentForChild to correctly compute the min intrinsic size.

This looks like a rounding difference. The new result matches the non-column result
in this same test, so it looks more correct to me.
