blis/testsuite/src/test_gemm.c
Field G. Van Zee fd5db714f4 Replaced use of bool_t type with C99 bool. 
Details:
- Textually replaced nearly all non-comment instances of bool_t with the
  C99 bool type. A few remaining instances, such as those in the files
  bli_herk_x_ker_var2.c, bli_trmm_xx_ker_var2.c, and
  bli_trsm_xx_ker_var2.c, were promoted to dim_t since they were being
  used not for boolean purposes but to index into an array.
- This commit constitutes the third phase of a transition toward using
  C99's bool instead of bool_t, which was raised in issue #420. The first
  phase, which cleaned up various typecasts in preparation for using
  bool as the basis for bool_t (instead of gint_t), was implemented by
  commit a69a4d7. The second phase, which redefined the bool_t typedef
  in terms of bool (from gint_t), was implemented by commit 2c554c2.
