blis/test/test_gemm.c
Field G. Van Zee ca9e435c57 Fixed a bug in reference implementation of dupl. 
Details:
- Fixed a bug in reference implementation of dupl (bli_dupl_unb_var1.c),
  which resulted in incorrect duplication.
- Updated old test drivers according to recently updated packm control tree
  creation interface.
- Added 'restrict' to x86 gemm microkernel interface.
