feat(minifier): do not flip if/else when it would produce longer result

[armano2]

Disable flipping of negated if statement when alternate is if statement

when if else if is encountered, flipping always produces at-least one extra character (in many cases 5) as new consequent has to be wrapped in {}, this also prevents remove_dead_code and minimize_statements to be run to covert if statement's to ternary expression

i'm not sure why ast changed after last merge, but that seem to be an issue on main, just ast
