Hi, Richard and Richi. Recently, we have some tries on our downstream RVV LLVM. We change "get_vector_length" (same IR like GCC "select_vl") into "umin", turns out LLVM SCEV analysis succeed. The unroll PASS works in LLVM.
I think Richard's suggestion is very reasonable. I didn't have the time take a look at how LLVM do now but I will take a look at it in the future.

I am gonna merge it after Richard's final approve. Thanks for checking, but no need to wait for a second ack from me! Please go ahead and commit. Richard
