  1. mass_attach: ensure we have straight-line execution to LBR capture 

    Using likely/unlikely hints, make sure we don't branch out before we
capture LBRs, which will ensure we don't waste LBR records unnecessarily
in --lbr=any mode.

  2. retsnoop: add full-lbr debug option to not filter LBR records 

    It makes it easier to see how many LBR records are "wasted" without
having to resort to --full-stacks, which produces raw addresses, making
output super wide.
