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): Clone trivial literals in sequential inliner ( #6005 )
...
**Description:**
As our minifier is two-pass by default, this is enough.
At the first pass, we inline all numeric literals using sequential inliner, and minifier can then inline constants correctly in the second pass.

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.
