refactor(es/minifier): Make rust-analyzer faster (#4744)
- We now use a separate crate for testing the minifier. This makes IDE much faster.

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.
