I just pushed https://github.com/dexonsmith/llvm-project/tree/perf/small-vector-specialize-reserveForParamAndGetAddressImpl, which should cause compile-time results to show up at http://llvm-compile-time-tracker.com/index.php?config=NewPM-O3&stat=instructions&remote=dexonsmith eventually, and we can see if there's a meaningful impact outside of the benchmark. Not sure whether it's worth changing `push_back()` since even on the toy benchmark it's not a big difference.

Results here:

Almost within the noise. One thing is "light green". @dblaikie , thoughts on whether it's worth landing? (I can send a Phab review)
