Details: - Replaced direct usage of _Pragma( "omp simd" ) in reference kernels with PRAGMA_SIMD, which is defined as a function of the compiler being used in a new bli_pragma_macro_defs.h file. That definition is cleared when BLIS detects that the -fopenmp-simd command line option is unsupported. Thanks to Devin Matthews and Jeff Hammond for suggestions that guided this commit. - Updated configure and bli_config.h.in so that the appropriate anchor is substituted in (when the corresponding pragma omp simd support is present).
