--- Comment #8 from ktkachov at gcc dot gnu.org ---
The issue in this bug report is that the "get low lane" operation should just
be a move rather than a vec_select so that it can be optimised away.
After g:e140f5fd3e235c5a37dc99b79f37a5ad4dc59064 GCC 11 does the right thing
for all testcases in this PR

So marking this as fixed.
