Perhaps I was quite too zelaous here (I've spent whole day playing around
with the branch prediction code, so I am quite tired at the moment).
Basically I want to have something like:
1) discover that this is conditional jump (in parallel or not)
  I've added nontrivial_condjump_p for this. I believe that originally
  testing of condjump_p and condjump_in_parallel_p was necesary
2) See the real jump (set of pc)
  I am having pc_set for this and I am not aware of any other function.
3) See whether it is safe to do some basic operations, such as removing
  of jump w/o getting surprises.

Maybe there are functions I am not aware of...
