Yes, I see it too in BucketFindAvx2
 0.67 ?      mov    %rdi,%r12

                    ?
  0.72 ?      sub    $0x18,%rsp                                                 
                    ?
  1.73 ?    ? callq  impala::BloomFilter::MakeMask(unsigned int)

Wondering if the multi-versioning attribute is still needed since MakeMask  
only called from BucketFindAVX2 and BucketInsertAVX2 which also have 
(__target__("avx2")).
