Handling of THRESHOLDs

  one drawback [with the new proposed scheme] is that we won't know any more
  which routine comes "after" a given threshold, for example after
  MUL_TOOM22_THRESHOLD could come either toom33 but also FFT. The best would be
  MUL_BASECASE_TOOM22_THRESHOLD.
    
I think I'll follow your suggestion, even if it leads to clunky names.
The three first names are REDC_1_TO_REDC_2_THRESHOLD
REDC_1_TO_REDC_N_THRESHOLD REDC_2_TO_REDC_N_THRESHOLD.
