Fix underflow when calculating the number of no-op jumps folded
When removing unwinds to no-op blocks and folding jumps to no-op blocks, remove the unwind target first. Otherwise we cannot determine if target has been already folded or not. Previous implementation incorrectly assumed that all resume targets had been folded already, occasionally resulting in an underflow: remove_noop_landing_pads: removed 18446744073709551613 jumps and 3 landing pads
