This comes as a followup to https://reviews.llvm.org/D53440, where I needed to test LoopUnrollOptions change and hence a way to specify a single pass instance having arguments different from a global configuration.
I can also imagine this being useful during bug triaging in some corner cases - our downstream pipeline uses different flavors of loop-unroll routinely.
