Let me ask a question, though, don't we want these asserts back too?

  assert(0 <= InterpreterBackwardBranchLimit,
         "OSR threshold should be non-negative");
  assert(0 <= InterpreterProfileLimit &&
         InterpreterProfileLimit <= InterpreterInvocationLimit,
         "profile threshold should be less than the compilation threshold "
         "and non-negative");

Also, why these are removed? Do they mess with buildability?

 102   bool reached_BackwardBranchLimit(InvocationCounter *back_edge_count) const {
 103     return (_counter & count_mask) + (back_edge_count->_counter & count_mask) >=
 104            (unsigned int) InterpreterBackwardBranchLimit;
 105   }
 106   // Do this just like asm interpreter does for max speed.
 107   bool reached_ProfileLimit(InvocationCounter *back_edge_count) const {
 108     return (_counter & count_mask) + (back_edge_count->_counter & count_mask) >=
 109            (unsigned int) InterpreterProfileLimit;


I see that InterpreterProfileLimit is gone, but InterpreterBackwardBranchLimit is still there,
should we keep the assert and reached_BackwardBranchLimit then?

Nothing new, just answer a few questions above.
