......................................................................
IMPALA-6645: Enable disk spill encryption by default
Perf:
Targeted benchmarks with a heavily spilling query on a machine
with PCLMULQDQ support show < 5% of CPU time spent in encryption and
decryption. PCLMULQDQ was introduced in AMD Bulldozer (c. 2011)
and Intel Westmere (c. 2010).
Testing:
Ran core tests with the change.
Updated the custom cluster test to exercise the non-default
configuration.
