Add support for Character Class Intersection in Regex forgery

[xgouchet]

Right now we do not support Character Class Intersection:

• /[a-m&&[g-x]]/ should have the same results as /[g-m]/
• /[a-m&&g-x]/ should have the same results as /[g-m]/
• /[a-m&&[^c-g]]/ should have the same results as /[a-bh-m]/
• /[a-z&&[aeiou&&[^c-g]]]/ should have the same results as /[aiou]/
