[v12.x] src: make --use-largepages a runtime option by gabrielschulhof · Pull Request #31063 · nodejs/node · GitHub

Moves the option that instructs Node.js to-remap its static code to
large pages from a configure-time option to a runtime option. This
should make it easy to assess the performance impact of such a change
without having to custom-build.
