I wonder at what point integer multiplication against a constant is faster than doing addition that many times

it's well documented that `i + i` is faster than `i * 2` in most cases

but does this hold for `i + i + i`? how about `i + i + i + i`?

@unascribed sounds like a job for compiler optimization

@noiob the context here is a PR to the Java JIT

so we *are* the compiler
