Feature #16837

## Problem How can we make Ruby 3.0 as fast as (or faster than) Ruby 2.7? ### Background * Split ruby.h https://github.com/ruby/ruby/pull/2991 added some new assertions * While it has been helpful for revealing various bugs, it also made some Ruby programs notably slow, especially Optcarrot https://benchmark-driver.github.io/benchmarks/optcarrot/commits.html ## Possible approaches I have no strong preference yet. Here are some random ideas: * Optimize the assertion code somehow * Enable the new assertions only on CIs, at least ones in hot spots * Not sure which places have large impact on Optcarrot yet * Make some other not-so-important assertions CI-only to offset the impact from new ones * Provide .so for an assertion-enabled mode? (ko1's idea) I hope people will comment more ideas in this ticket.
