Increased MT sup threshold for double to 180.

Browse Source 
Details:
- Increased the double-precision real MT threshold (which controls
  whether the sup implementation kicks for smaller m dimension values)
  from 80 to 180, and this change was made for both haswell and zen
  subconfigurations. This is less about the m dimension in particular
  and more about facilitating a smoother performance transition when
  m = n = k.
