Field G. Van Zee c31b1e7b9d Relax alignment restrictions for sandybridge ukrs.
Details:
- Relaxed the base pointer and leading dimension alignment restrictions
  in the sandybridge gemm microkernels, allowing the use of vmovups/vmovupd
  instead of vmovaps/vmovapd. These change mimic those made to the haswell
  microkernels in e0d2fa0 and ee2c139.
- Updated testsuite modules as well as standalone test drivers in 'test'
  directory to use DBL_MAX as the initial time candidate. Thanks to Devin
  Matthews for suggesting this change.
- Inserted #include "float.h" into bli_system.h (to gain access to DBL_MAX).
- Minor update (vis-a-vis contexts) to driver code in test/3m4m.
