feat(minifier): inline single-use variable past read-only variables (#14184) fixes #13912 As long as we know the variable is not re-assigned, the value is same even if we reordered the expression. By using that fact, we can compress ```js function wrapper() { var x = foo, y = bar; return [x, y] } ``` to ```js function wrapper() { return [foo, bar] } ``` .
