Details:
- Renamed the following C preprocessor macros whose fallback/default
values are specified within frame/include/bli_kernel_macro_defs.h:
BLIS_DEFAULT_MR_THREAD_MAX -> BLIS_THREAD_MAX_IR
BLIS_DEFAULT_NR_THREAD_MAX -> BLIS_THREAD_MAX_JR
BLIS_DEFAULT_M_THREAD_RATIO -> BLIS_THREAD_RATIO_M
BLIS_DEFAULT_N_THREAD_RATIO -> BLIS_THREAD_RATIO_N
- Renamed the above cpp macro overrides within the knl, skx, and zen
sub-configurations, as well as invocations of those macros in
bli_rntm.c.
- Moved config/zen/bli_kernel.h to an 'old' directory as it is no longer
used by any code within BLIS.
