This extra use strict is not need (it also does no harm)

src/collection.js:58: if (keyIsNaN && IS_NUMBER(candidate) &&
NUMBER_IS_NAN(candidate)) {
IS_NUMBER(x) && NUMBER_IS_NAN(x)
is repeated in a few places. Maybe we can introduce a new macro for
this?

src/collection.js:88: return (field >>> 2 /* Name::kHashShift */);
skip parens here

src/collection.js:128: if (IS_NUMBER(key) && key === 0) {
This needs a comment and preferably a bug number.
