Patch rebased.

> It looks like LSR can surely find improvement here, at least for the code-gen I observed from your test case on the RISC-V backend.

I agree, but we need to find real benchmark improvements to motivate this, I think...

> Other than the rebase, may you add debug logs to show the changes for your enhancement, thanks for the work!

I will do that later if there is an interest for the patch being committed...
