feat(es/minifier): Ignore return values of ignored IIFEs ( #6020 )
...
**Description:**
As we are not using the return value of the function, we can call `ignore_return_value` on the argument of the return statements of IIFE.

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.
