[llvm] Sort by benefit to cost ratio (PR #90264)

https://github.com/xuanzh-meta created https://github.com/llvm/llvm-project/pull/90264
We changed the order in which functions are outlined in Machine Outliner.
The formula for priority is found via a black-box Bayesian optimization toolbox. Using this formula for sorting consistently reduces the uncompressed size of large real-world mobile apps. We also ran a few benchmarks using LLVM test suites, and showed that sorting by priority consistently reduces the text segment size.
