After using enum class, a switch-case warning in CombineBreakType is caught.
This is one of such kind safty checks that we would like to gain.
Fix it by adding default case for switch-case in CombineBreakType.

With this change, we could export BreakTypeToString() to other files that desire
to print break type for debugging.

This should've been covered in Bug 956447. The declaration is already behind
DEBUG_FRAME_DUMP in nsLineBox.h. Just move the implementation to agreee with that.

NS_STYLE_CLEAR_NONE has been defined to 0 for like forever, so this code should
never be run. Remove it.

Structs in our style system use an arena-style allocation system,
managed by the presshell to which they belong. All of the relevant
overloads that forward allocation requests to the presshell declare
themselves as CPP_THROW_NEW, which indicates that they do not throw
exceptions. The C++ specification states that operator new overloads
that declare themselves to not throw exceptions require a null check on
their return value. However, the relevant presshell allocation method,
AllocateByObjectID, is infallible and will never return a null pointer.
The callers of all of these methods are therefore doing useless
(compiler-generated) null checks. Let's get rid of those useless checks
by removing the CPP_THROW_NEW annotations. This change declares these
methods will return non-null pointers and throw exceptions in case of
errors--but as we don't use exceptions, and AllocateByObjectID will
abort on OOM, everything works out OK.

AllocateByObjectID() is infallible. Therefore the |operator new| of nsFrameList,
nsLineBox and nsRuleNode are too, as is nsRuleNode::CreateRootNode().
The patch also removes a couple of comments duplicated in both .h and .cpp
files.

Rename NS_STYLE_CLEAR_LEFT_AND_RIGHT to NS_STYLE_CLEAR_BOTH. Also fix whitespace and remove unnecessary parens in a few places and enumerate the possible break types in an assertion so that it doesn't make assumptions on the actual property values.
Specifically:
* move all the frame dump methods to nsIFrame. Especially nsFrame::ListTag
was annoying, often requiring a cast to nsFrame*.
* print common values in the same order for all types of frames
* print fluid continuations as "next-in-flow=%p" and non-fluid as
"next-continuation=%p" (as before)
* print the style-context more compactly, e.g.
"[sc=0x7faa6b60e0a0] pst=:first-line" becomes
"[sc=0x7faa6b60e0a0:first-line]"
* suppress printing visual/scroll-overflow rects when they are identical
to mRect and do the same for nsLineBox::List where it was especially
hard to see which lines actually had real overflow
* fix a bug that printed the child list name at the far right when the
principal list was empty (making it hard to see)
* print the address of child lists (other than the principal list) to
help debug frame list property bugs
