  > > This adds an explicit {OsrPoll} bytecode into every loop header which
  > > triggers on-stack replacement when armed. Note that each such bytecode
  > > stores the static loop depths as an operand, and hence can be armed for
  > > specific loop depths.
  > >
  > > This also adds builtin code that triggers OSR compilation and switches
  > > execution over to optimized code in case compilation succeeds. In case
  > > compilation fails, the bytecode dispatch just continues unhindered.
