Added test cases for 1 and 2 in the pre-commit [PR](https://github.com/llvm/llvm-project/pull/83780) so the diff in this one is clearer.

As discussed offline, non-count prof data (i.e., representing taken or not taken branches, associated with `br` or `switchinst`, etc) doesn't need scaling so no extra work needed. PTAL.
