LOG: [LVI] Remove unused get of Range metadata (#94914)

There is no test for this code and it also do not change the result of
https://github.com/dtcxzyw/llvm-opt-benchmark when I run it locally.
I have not been able to make a test for this and do not know how to
handle the range attribute for this so maybe it shall be removed?
