[BUG] js_of_ocaml is not aware of the BigInt API

[msprotz]

Describe the bug
Spurious warnings about free variables in my overrides:

warning: free variables in primitive code "uint128_mul" (/Users/jonathan/Code/mls-proposals/_build/default/js/overrides.js:520)
vars: BigInt

Expected behavior
js_of_ocaml should have a built-in knowledge of the BigInt object, see https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/BigInt

Versions
3.9.1
4.11.1

Thanks,

Jonathan

You can always use joo_global_objet.BigInt

Ah that's a good workaround for the time being; thanks!
