More memory alignment-related tweaks.

Browse Source 
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).
