enable-checking failure record_insns () and PARALLEL

[grahams]

Hi

I'm getting a enable-checking failure using the current CVS on 
i686-linux bootstrapping with "-O3 -mcpu=pentiumpro -march=pentiumpro
 -fomit-frame-pointer"

The bootstrap fails because record_insns () is being passed a rtx
which is a PARALLEL which causes INSN_UID (insns) to abort.

Question. Should record_insns () handle the parallel or does this
indicate a bug elsewhere?
