compiler: only build thunk struct type when it is needed

Instead of building the thunk struct type in the determine_types pass,
build it when we need it.  That ensures that we are consistent in
determining whether an argument is constant.

We no longer need to add a field for a call to recover, as the
simplify_thunk_statements pass runs after the build_recover_thunks pass,
so the additional argument will already have been added to the call.

The test case is https://go.dev/cl/440297.

Fixes golang/go#56109
