yangguo d1f68f776e [regexp] fix bogus assertion in CharacterRange constructor.
The CharacterRange constructor checks the input for validity. However,
CharacterRange::Singleton also uses the constructor and may have
kEndMarker as input, causing the check to fail.

The solution is to move the check to CharacterRange::Range and
consistently use it across the code base.
