Patch to fix record_insns/--enable checking failure

[Jan Hubicka <hubicka at atrey dot karlin dot mff dot cuni dot cz>]

Hi
This patch fixes record_insns call to get always an insn or seqence
and fixes the --enable-checking failures.
When the expander don't return seqence, insn needs to be emited first
in order to get (INSN around and INSN_UID to work.
