[X87] [crankshaft] Always use Label:kFar as lable dist in DoWrapReceiver() for debug mode.

  Currently In LCodeGen::DoWrapReceiver(), the x87 jitted code's size for debug mode between label's define and bind
  exceeds 128 bytes whether FLAG_deopt_every_n_times is set or not.

  So always use Label:kFar as label distance in LCodeGen::DoWrapReceiver() for debug mode.

  This CL also unify the label's distance value to avoid potential bugs caused by unconsistent distance value usage
  for the same label when DeoptEveryNTimes() return true.
