Details: - Renamed BLIS_MEMORY_ALIGNMENT_SIZE to BLIS_CONTIG_MEM_ALIGN_SIZE. - Renamed BLIS_ENABLE_MEMORY_ALIGNMENT to BLIS_ENABLE_SYSTEM_MEM_ALIGN. - Added BLIS_SYSTEM_MEM_ALIGN_SIZE, which controls only the alignment passed into posix_memalign() or equivalent. - Defined new function, bli_align_dim_to_cmem(), which applies the contiguous memory alignment (rather than the system/malloc alignment).
