Subject: [LoopVer] Add missing std::move
X-Git-Url: http://plrg.eecs.uci.edu/git/?a=commitdiff_plain;h=77907c75553b579e774ad29cccf9882374fb6c70;p=oota-llvm.git

[LoopVer] Add missing std::move

The reason I was passing this vector by value in the constructor so that
I wouldn't have to copy when initializing the corresponding member but
then I forgot the std::move.

The use-case is LoopDistribution which filters the checks then
std::moves it to LoopVersioning's constructor.  With this interface we
can avoid any copies.
