Details: - Renamed the microkernels in kernels/zen/3 to kernels/haswell/3 and then updated the file contents to use the 'haswell' infix. - Updated bli_cntx_init_zen.c and bli_cntx_init_haswell.c according to above function renames. - Moved/updated the corresponding prototypes in bli_kernels_zen.h to bli_kernels_haswell.h. - Updated config_registry according to above changes. - NOTE: This rename reflects the fact that haswell microkernels are specifically written to overcome the floating-point latency for FMA instructions on Intel Haswell-like architectures, which can issue two FMA instructions per cycle. These ukernels happen to work fine on AMD Zen-based architectures. However, Zen only issues one FMA per cycle, which, while halving its floating-point throughput, gives it extra flexibility in the design of its microkernels--namely, mr and nr can be smaller and still overcome the floating-point latency for those single-issue cores. A smaller value of mr and nr allows for a larger value of kc, which may be useful in some situations. In the future, we may write such Zen-specific microkernels to take advantage of this additional flexibility.
