// This module declares an indirect call (`f(x)` in `apply`) but never takes a
// concrete function as a value, so `fn_value_indices` stays empty. The indirect
// function table must still be emitted, otherwise the `call_indirect` references
// a table that does not exist and the module fails to validate.
