Similar to Selection::Collapse(), if mCachedRange is available,
Selection::SetBaseAndExtent() should use it rather than creating new nsRange
instance.
Then, it can reduce the allocation cost and may reduce some other cost, e.g.,
adding it to mutation observer.

When setting value of <input type="text">, nsTextEditorState removes all
ranges of normal selection first. Then, TextEditor sets the value. Finally,
TextEditor collapses the selection at the end of the text.
In bug 1386471, we got that there are some problems to remove the call of
Selection::RemoveAllRanges() in nsTextEditorState. Therefore, we need another
approach to improve Selection::Collapse().
The approach of this patch is, when removing all ranges from normal selection,
Selection can cache an nsRange instance if there is an instance which is not
referenced from other than the Selection (i.e., it'll be removed when
Selection::Clear() is called). Then, Selection::Collapse() can reuse it. With
this fix, Selection::Collapse() can reduce allocation cost and may reduce some
other cost like adding it to mutation observer.
However, keeping nsRange instance may cause increasing mutation observer's cost
since nsRange will be adjusted its start node/offset and end node/offset with
mutation observer to guarantee that the range is always valid. So, we can
cache such range only when the caller (or its callee) will set selection range
later. Therefore, this patch adds Selection::RemoveAllRangesTemporarily()
and make only nsTextEditorState::SetValue() and
ContentEventHandler::OnSelectionEvent() use it.

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.

nsTextEditorState stores selection controller as
RefPtr<nsTextInputSelectionImpl> mSelCon. However, some methods still use
nsTextInputSelectionImpl::GetSelection(RawSelectionType, nsISelection**) which
is a virtual method overriding nsISelectionController.
So, instead, we should make it use
nsTextInputSelectionImpl::GetSelection(SelectionType).

nsIHTMLEditor has several scriptable methods (addDefaultProperty(),
removeDefaultProperty(), etc.) that have nsIAtom parameters. We're in the
process of deCOMtaminating nsIAtom (bug 1392883) so these methods need to be
changed.
This patch does the following.
- It changes those methods to take an AString instead of an nsIAtom.
- For each existing method, it adds to HTMLEditor a new C++ method of the same
name that takes an nsIAtom parameter.
- It updates TextEditorTest.cpp to use strings instead of atoms, in order to
keep using the XPIDL methods.
- It updates test_bug1140105.html to pass strings instead of atoms to
getInlineProperty(). This removes the use of nsIAtomService.

The debug info object is only allocated if, when the Promise is created, either async stacks are enabled or the Promise is created in a debuggee compartment.

Bug 1360308 offloads IO operations from the main thread when we create paired minidumps.
This breaks the symmetry of paired minidumps: the thread stacks of the parent minidump
doesn't correspond to the thread stacks in the child minidumps and renders the parent
stack useless. This patch moves generation of the parent minidump back to the main
thread to keep the context of the parent process when creating paired minidumps. Child
minidump is still created asynchronously.
