We agreed in D10555 that, as long as we don't affect -O0 codegen too much, it's
OK to use native constructs rather than intrinsics. Let's test that, starting
with AVX2
RKSimon added a comment.
Definitely like this idea - hopefully it'll make it safer to remove unnecessary
builtins.

This revision is now accepted and ready to land.
LGTM with a suitable FIXME comment. Email me if you want to split the work on
adding this to the other SSE/AVX builtin tests.

Thanks Simon! Replaced the FIXMEs with proper tests and committed.
Whenever I have time I'll have a look at the others, filed PR24580.
