compiler: use bool for comma-ok if not already boolean

If a comma-ok variable already has a type, and that type is not a
boolean type, then set the type of the temporary variable to bool.
Otherwise we may try to convert an unnamed bool type to an interface
type, which will fail. But we don't want to always use bool, because
the type of the comma-ok variable may be a named bool type, in
which case the assignment would fail (or need an explicit conversion).

The test case is https://go.dev/cl/404496.

Fixes golang/go#52535
