Details: - Adjusted the definition for libblis_test_get_string_for_result() in testsuite/src/test_libblis.c so that the "FAIL" string is returned if the computed residual contains either NaN or Inf. Previously, a residual containing NaN would result in the selection of the "PASS" string. Thanks to Devin Matthews for reporting this issue (#279). - Expounded on comment for the macro definitions of bli_isnan() and bli_isinf() in bli_misc_macro_defs.h to make it more obvious why they must remain macros.
