It does not apperas to be realted to cfgcleanup.  The purpose of failure
is that we unroll loop containing instruction having REG_LABEL referencing
insn outside. While updating references to insns it aborts on reference
to insn outside unrolled loop.
I am not quite sure why it didn't happen previously - perhaps as a result
of strengthtened gcse, but it looks valid transformation to me and I
believe I need just avoid the abort.
