blis/test/3/test_gemm.c
Field G. Van Zee b938c16b0c Renamed test/3m4m to test/3.
Details:
- Renamed '3m4m' directory to '3', which captures the directory nicely
  since it builds test drivers to test level-3 operations.
- These test drivers ceased to be used to test the 3m and 4m (or even
  1m) induced methods long ago, hence the name change.
