Inlined IIFEs have the exact pattern sequential inliner wants, so it's good to invoke it.

feat(es/minifier): Inline lazily initialized variables ( #5737 )
...
Safety:
For a function-local variable, an expression with side-effects would be a call, including an indirect one with a member expression.
- If the call is function-local, it will be analyzed by the analyzer and inliner will not work.
- If the call is not a function-local one, it cannot modify the local variable.
