Here is an updated version with disabled alias checks for loop epilogues.
Instead of calling vect_analyze_data_ref_dependence I just use VF of the
original loop as MAX_VF for epilogue.
Thanks,

I know Richi wasn't all that happy with the call into if-conversion and
I don't particularly like the use of aux for smuggling data around. But
I think those are warts, not fundamental design flaws.
OK once the rest of the bits are approved.
