go_1_18: backport CL417615

Upstream reverted cmd/compile: revert "fix missing dict pass for type
assertions", as it's causing compilation errors in programs like gopass
- see https://github.com/gopasspw/gopass/issues/2280 and
https://github.com/NixOS/nixpkgs/issues/182440.

The revert has already been cherry-picked to HEAD, but there's no
backport release yet. This can be reverted once there's a new release
with that commit.
