[whatwg] 2.2 Performant

[Elliotte Rusty Harold]

"In particular, the algorithms defined in this specification are
intended to be easy to follow, and not intended to be performant."

Yech. The recently coined word "performant" just grates on my ears;
and I'm not the only one as a Google search will show:

Perhaps we could replace it with "efficient" or some other word or phrase?
