Not sure it's possible to merge DF_REG_DEF_CHAIN walk and
DF_REF_CHAIN walk...

This is an attempt to extend RTL unroller to allow cases like mentioned in the

namely when loop has duplicated exit blocks and back edges.
Bootstrapped and regtested on x86_64, also checking wide range of benchmarks -
spec2K, spec2006, EEMBC
