Introduced as part of v16.0.0 and v14.18.0, this allows redundant require.cache calls to be bypassed for builtin modules, saving a few yoctoseconds.

See https://nodejs.org/api/modules.html#core-modules and discussion in nodejs/node repo regarding why require.cache calls are redundant for builtins.

Bit stumped on the test failure. :|

Looks like tests are unhappy prior to this change anyway. Just updated the samples 54c404f, which have no bearing on anything, and the CI fails.
