This broke our Ubuntu bot (clang-3.8 with libstcd++-5.4)


./../Source/JavaScriptCore/bytecode/UnlinkedCodeBlock.h:312:16: error: chosen constructor is explicit in copy-initialization
        return { profile, recommendedIndexingType };
               ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
/usr/bin/../lib/gcc/x86_64-linux-gnu/5.4.0/../../../../include/c++/5.4.0/tuple:612:19: note: constructor declared here
        constexpr tuple(_U1&& __a1, _U2&& __a2)
                  ^
1 error generated.

There probably just needs to be a WTFMove around profile and recommendedIndexingType.

That didn't worked.. I was only able to fix the build error by reverting changes of  r233065 over UnlinkedCodeBlock.h

I have submitted a patch for fixing this at bug 187051 .. if you can review it that will be great.
