First of all, thanks for your contribution @Abhishek-Varma 

Now, I am afraid I cannot subscribe to any large code changes to tiling transforms until #77874 is addressed to my satisfaction. I already gave a pass 6 months ago and another one 3 months ago when things were supposed to be addressed "in short order". 

We're now past tech-debt reduction time: 
1. first let's address #77874, 
2. then let's address the reuse as also pointed out by @ftynse 
```
All of this code looks very similar to the scf.for case. Is it possible to hoist it out into a helper function, potentially with templates?

More generally, the entire 1,2,3,4, ... thing here could be a sequence of calls to appropriately named and documented functions. But not blocking on this one, only hoisting out long blocks of common code.
```

Thanks for helping move this forward!


At this time, more copy-pasta of code is unwelcome. Let's first reduce the duplication
