Details: - Expanded on cpp macro definitions from bli_mem.c and relocated them to a new header file, frame/include/bli_mem_pool_macro_defs.h. The expanded functionality includes computing the pool size for each datatype (using that datatype's cache blocksizes) and using the maximum to size the actual pool array. This addresses the somewhat common pitfall whereby a developer updates cache blocksizes in bli_kernel.h for only one datatype (say, single-precision real), while the memory pools are sized using the double-precision real values. Then, when the developer attempts to link to and run a level-3 BLIS routine (e.g. dgemm), the library aborts with a message saying the static memory pool was exhausted. Clearly, this message is misleading when the pool was not sized properly to begin with. - Removed previously disabled code in bli_kernel_macro_defs.h that was meant to check for size consistency among the various cache blocksizes. (Obviously the memory pool size-based solution mentioned above is better.) - Added BLIS_SIZEOF_? cpp macros to bli_type_defs.h. This seemed like a reasonable place to put these constants, rather than further crowd up bli_config.h. - Updated testsuite driver to output memory pool sizes for A, B, and C. - Minor comment updates to bli_config.h. - Removed 'flame' configuration. It was beginning to get out-of-date, and I hadn't used it in months. We can always re-create it later.
