On GCC 8.x, the r248351 fixed this.

cfgcleanup: Ignore clobbers in bb_is_just_return
The function bb_is_just_return finds if the BB it is asked about does
just a return and nothing else. It currently does not allow clobbers
in the block either, which we of course can allow just fine.
This patch changes that.
* cfgcleanup.c (bb_is_just_return): Allow CLOBBERs.
