Add vzeroupper to Haswell microkernels. (#524)

Browse Source

Details:
- Added vzeroupper instruction to the end of all 'gemm' and 'gemmtrsm' 
  microkernels so as to avoid a performance penalty when mixing AVX
  and SSE instructions. These vzeroupper instructions were once part 
  of the haswell kernels, but were inadvertently removed during a source 
  code shuffle some time ago when we were managing duplicate 'haswell' 
  and 'zen' kernel sets. Thanks to Devin Matthews for tracking this down 
  and re-inserting the missing instructions.
