func IgnoreFields(typ interface{}, names ...string) cmp.Option {
	sf := newStructFilter(typ, names...)
	return cmp.FilterPath(sf.filter, cmp.Ignore())
}
IgnoreFields returns an Option that ignores exported fields of the
given names on a single struct type.
The struct type is specified by passing in a value of that type.

The name may be a dot-delimited string (e.g., "Foo.Bar") to ignore a
specific sub-field that is embedded or nested within the parent struct.

This does not handle unexported fields; use IgnoreUnexported instead.
