Another way to do it is to not return here, create an else branch to wrap the stuff below and leave the initialization to initSearchParams(this[searchParams], search) later. That way URL doesn't need to know about the data sturcture of URLSearchParams

@joyeecheung, done, PTAL.
This does bring a drop to performance when !search. To counter this problem I added a few conditions to avoid parsing as much as possible.
After those changes, when alternative is changed to '', there is a 2.8% drop in performance; but when it is '?' there is a 400% increase, as measured by
node benchmark/compare.js --new ./after --old ./orig \
--set n=1e5 --set prop=search --set 'url=http://example.com/' \
--filter properties urlThat's pretty good IMO.

Will this make it to a 7.5.1 or will it have to wait for 7.6? |

Unsure. It depends on when 7.5.1 goes out. This won't land until Friday following our typical 48 hour cycle |

We can probably just get rid of the comment now, or mention search in it.
