Hi @m-sai 
@nikic pointed me to this patch on https://discourse.llvm.org/t/missed-loop-peeling-and-thus-vectorization-opportunity/80616. This patch is indeed fixing the vectorization issue in the TSVC benchmark. 

Overall, this patch looks good to me as I arrived at some of the changes myself in my local branch :) - adding PHI nodes as a starting point is sensible.

I have another test case from TSVC benchmark but I believe I can add it after you land this patch.
