@xiaochengh 
There is some functions in EditingUtilities only used in one place:
For example:
bool IsEmptyTableCell(const Node*);
Only used in SelectionAdjuster.cpp.
Is it OK to move IsEmptyTableCell to SelectionAdjuster.cpp as a local function?

Make IsEmptyTableCell() be a local function in SelectionAdjuster.cpp.

Move IsEmptyTableCell() out of EditingUtilities for better code
structure.

Move IsAmbiguousBoundaryCharacter() out of EditingUtilities.

IsAmbiguousBoundaryCharacter() only used in SpellChecker.cpp, move it
from EditingUtilities to SpellChecker.cpp for better code structure.
