G1Policy::update_young_length_bounds currently only gets the current remembered set length (estimate) passed directly.
Add the number of pending (log buffer) cards to the signature as both remembered set length and log buffer cards are significant (often the most significant) contributors to calculating pause time length.
This allows passing current (actual) pending cards number instead of using the prediction when revising young gen size too.
