We'd need some code to benchmark this. Presumably something that does
a lot of long long conditionals.
I'd hoped the linux kernel would be a good test, but only 11 files were
affected by the change and only one of those files had a change in the
size of the text segment (improved by a half-dozen or so bytes).
Maybe the gnu-mp or glibc would be a reasonable test?!?
