My first thought WRT the actual patch itself is why not put the logic to fixup
the insn chain for SEQUENCEs at the end of reorder_insns_nobb?  That would
avoid similar problems for any other code that used this function after reorg.c
had started.

It also seems to me there are 4 cases that need to be fixed.

FROM is a SEQUENCE
  Need to fix PREV_INSN of the first insn in the SEQUENCE

TO is a SEQUENCE
  Need to fix NEXT_INSN of the last insn in the SEQUENCE

PREV_INSN (FROM) is a sequence
  Need to fix NEXT_INSN of the last INSN in the SEQUENCE

NEXT_INSN (TO) is a sequence
  Need to fix PREV_INSN of the first INSN in the SEQUENCE

Am I missing something here?
