> "Safe" fix:
No, no... pextr to a temporary should be used here.
I plan to introduce pextr handling to "insv<mode>" pattern. Then,
ix86_expand_pinsr will call ix86_expand_pextr for non-lowpart src subregs (and
in a similar way, new ix86_expand_pextr will call ix86_expand_pinsr for
non-lowpart dst subregs).
