Bug 1608771 addresses fast Ion to Wasm calls with BigInt/I64 calls, but patches for the bug don't implement it for 32-bit platforms. A patch was attempted for this case (https://phabricator.services.mozilla.com/D65240) but it was abandoned because of its complexity (due to I64 arguments getting split into multiple arguments, which complicated lowering to LIR and code generation). It could be useful to solve this limitation in the future, as discussed in the patch's review comments.

Obviously it's nice to have this but we can live without 32-bit support => P3.
