--- Comment #21 from Sanjay Patel <spatel+llvm at rotateright.com> ---
And finally:
https://reviews.llvm.org/D41714
https://reviews.llvm.org/rL321934

This goes beyond what was requested in this report to use 2
load-pairs-per-block for all enabled 'memcmp() == 0' expansions (including
smaller scalar expansions). 

That looks better in theory, but we'll see if anyone reports perf problems from
that change.
