Added basic flop-counting mechanism (level-3 only).

Browse Source 
Details:
- Added optional flop counting to all level-3 front-ends, which is
  enabled via BLIS_ENABLE_FLOP_COUNT. The flop count can be
  reset at any time via bli_flop_count_reset() and queried via
  bli_flop_count(). Caveats:
  - flop counts are approximate for her[2]k, syr[2]k, trmm, and
    trsm operations;
  - flop counts ignore extra flops due to non-unit alpha;
  - flop counts do not account for situations where beta is zero.
