As long as your friend still has proof of her legal entry and presuming that her boyfriend is a US citizen, the existing immigration law allows her to stay in the US and apply for her green card after getting married. The fact that she overstayed her visa will not affect her application. In fact, she should not leave the country until she gets her green card.
As for the bills pending before Congress, nothing has been passed into law yet, so it’s too early to even speculate about any eventual new application procedure.
