feat(es/minifer): Improve minifier ()
swc_ecma_minifier:
 - `if_return`: Allow side-effect-free statements to come after `if_return`.
 - `collapse_vars`: Move variables without init to first.
 - `analyzer`: Remove useless fields.
 - Don't drop `return` tokens if there's a finally block.
 - `drop_return_value`: Drop side-effect-free return arguments.
 - `make_sequences`: Don't inject `void 0` to return args.
 - `if_terminate`: Move to the pure optimizer.
 - Fix a bug related to `RegExp`.
