Subject [Impala-ASF-CR] Add FNV, Zobrist, and SIMD hash functions to the int hash benchmark.
Date Tue, 06 Sep 2016 01:36:33 GMT
Jim Apple has uploaded a new change for review.

Change subject: Add FNV, Zobrist, and SIMD hash functions to the int hash benchmark.
......................................................................

Add FNV, Zobrist, and SIMD hash functions to the int hash benchmark.

Additionally, change the parameter of rotate to a compile-time
constant, and add "inline" to functions, increasing the performance
dramatically. The compiler can't inline the SIMD versions, because
they use Intel intrinsics -- added a TODO to add these intrinsics to
sse-util.h.
