test(es/minifier): Organize terser tests (#6116) 
**Description:**

Our minifier is better than terser in some cases, so we don't need to match the output of terser exactly.

feat(es/minifier): Drop vars from sequential inliner (#5993) 
**Description:**

This PR renames `CloningMultiReplacer` to `Finalizer` and makes it handle the removal of unused variables. Also, this PR improves the sequential inliner so we can drop variables within a single pass.

feat(es/minifier): Invoke sequential inliner for inlined IIFEs (#5991) 
**Description:**

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

feat(es/minifier): Ignore more expressions in sequential inliner (#5961) 
**Description:**

We can skip **member access** to `console` as it does not have any side effects.

test(es/minifier): Categorize terser tests (#5960) 
**Description:**

I'm going to focus on rules enabled by default. I updated some tests because our one was better, and postponed `unsafe` tests.

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.

feat(es/resolver): Use different syntax context for unresolved refs (#4436) 
- We don't need a list of bindings to check if an identifier is unresolved.
 - Checking if an identifier is unresolved is now one CPU instruction.
   - Previously it was one hashmap operation.
 - This PR also improves performance, by removing the hashmaps mentioned above.
