Subject: -Wdeprecated-clean: Fix cases of violating the rule of 5 in ways that are deprecated... 
X-Git-Url: http://plrg.eecs.uci.edu/git/?p=oota-llvm.git;a=commitdiff_plain;h=b80eede6419ce4fa011bd1b27aae1c76ce2a2f3f

-Wdeprecated-clean: Fix cases of violating the rule of 5 in ways that are deprecated in C++11

Remove some unnecessary explicit special members in Hexagon that, once
removed, allow the other implicit special members to be used without
depending on deprecated features.
