Alignment of polyfill names to real polyfill collections

[robatwilliams]

They're currently aligned with no particular strategy, probably mostly with how detection is implemented.

e.g. 'String.prototype.trimEnd', 'String.prototype.trimLeft', 'String.prototype.trimRight', 'String.prototype.trimStart',

Those are actually distributed as a single polyfill. Would be better to just have to specify one thing rather than the 4 individually.

Would be a breaking change, albeit not particularly inconvenient.
