In the years since https://codereview.chromium.org/1331993004, a lot has
changed in v8: Math.max/min are now CSA builtins, with lowerings in
TF.

In a quick test on my machine of the microbenchmark on that CL
(modified with start and end values), I don't detect any difference
in speed between the macro versions on master and this version.
