Bug 1400459 devirtualized nsIAtom so that it is no longer a subclass of
nsISupports. This means that nsAtom is now a better name for it than nsIAtom.

GetIndexFromSelectionType() in nsFrameSelection.cpp or
nsFrameSelection::GetSelection() appears in profile of attachment 8848015. So,
it should not use switch statement due to really hot path.
With the previous patch, we can make it use array to retrieve the index from
SelectionType with static_cast<int8_t>.

nsISelectionController::SELECTION_* are declared as bit-mask. However, no
methods of nsISelectionController treat them as bit-mask and these
values need a switch statement in nsFrameSelection to convert SelectionType to
array index of nsFrameSelection::mDOMSelections because it's too big to create
an array to do it. Additionally, this conversion appears profile of
attachment 8848015.
So, now, we should declare these values as sequential integer values.
However, only nsTextFrame uses these values as bit-mask. Therefore, this patch
adds new type, SelectionTypeMask and creates new inline method,
ToSelectionTypeMask(SelectionType), to retrieve mask value for a SelectionType.

nsContentUtils::GetHTMLEditor() currently returns nsIEditor* since editor of doc shell may be any type of editors such as TextEditor or editor object which is implemented by JS. However, nsIEditor is now a builtin class. So, it can return HTMLEditor.

This does NOT change variable names like |startNode| because it's not odd and somebody use it for nsINode and startContent for nsIContent. So, changing them needs more work.
