Created an attachment (id=8507)
 -- (http://gcc.gnu.org/bugzilla/attachment.cgi?id=8507action=view)
proposed patch

This implements a similar dependency check as in emit_libcall_block,
except that we might have to consider multiple sets / clobbers.
This also fixes the bogosity of checking only the first set for
setting part of target, and looking at the SET_DEST of USEs and CLOBBERs.
