hash_scan_insn has the comment:
Single sets in a PARALLEL could be handled, but it's an extra
complication that isn't dealt with right now. The trick is handling
the CLOBBERs that are also in the PARALLEL. Later.
Is this comment still valid ..
I don't think so.
it doesn't match the current implementation. Actually the current
implementation appears to be busted since it records multiple sets
which is preventing me from building an ARM cross compiler. I'm about
to put together a patch for that problem which I believe is due to:

* gcse.c (hash_scan_insn): Clean up calls to hash_scan_set.
If you send me a .i file and the configuration name, I'll be glad to take
a look at it if you can't fix it.
