[Bug target/68793] Bad optimization by split-wide-type on NEON

--- Comment #5 from Allan Jensen <linux at carewolf dot com> ---
The test-case uses C++11 initialization. I haven't tested gcc 6, so if you say
it is solved, I would trust you.

Note the 32-bit case is also suboptimal in both cases (not affected by
split-wide-types). Is that also fixes in gcc 6?
