Transform static method calls into consts

[rentalhost]

Describe the feature

In case where static method calls can be simplified to const.

For instance:

export const example = (x) =>
  Math.min([
    Math.max(1, x),
    Math.max(2, x)
  ]);

Could be transformed into:

const Math_max = Math.max;

export const example = (x) =>
  Math.min([
    Math_max(1, x),
    Math_max(2, x)
  ]);

With mangle top level:

let t = Math.max;

export const example = (x) =>
  Math.min([
    t(1, x),
    t(2, x)
  ]);

Note that only Math.max() is affected, as it occurs multiple times. However, there is a ~20% performance gain, so we can do the same for Math.min():

const Math_min = Math.min;
const Math_max = Math.max;

export const example = (x) =>
  Math_min([
    Math_max(1, x),
    Math_max(2, x)
  ]);

With mangle top level:

const t = Math.min;
const a = Math.max;

export const example = (x) =>
  t([
    a(1, x),
    a(2, x)
  ]);

---

• Pro: ~20% performance
• Pro: code reduction for bigger codes / a lot of usages;
• Cons: code increase for small codes / few usages;

My suggestion is create as a new option for "compress" group, but disabled by default. Or then a way to check when is advantage do that automatically.

There is a significant con to doing this - in JS every builtin can be overridden (Math.max = somePolyfill).
