**Description:**

Invoke DCE only before the first compression. I verified that this patch does not affect the compression rate of the real-world inputs greatly.

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.

fix(es/minifier): Fix evaluation of IIFEs (#4207)
- We now remap parameters using a new syntax context. This is required because we may copy functions, and it can result in duplicated variables with respect to the span hygiene.
 - We now visit the sequence expression generated by inlining. This is to improve performance in some cases.
 - We now remove variables from variable statements if it's identical to a parameter declared in the function.
 - IIFE evaluation is now aware of `this` being different for member expressions.
 - We now have more logic for detecting simple functions.
