Ignore more types in no-fn-reference-in-iterator and no-reduce rule

[fisker]

• Ignore more types that can't be a function on no-fn-reference-in-iterator and no-reduce rule.

Including some unsafe node types, like

a.find(a = fn);
a.find(await fn);
a.find(fn());
a.find(fn1 || fn2);
a.find(new Foo());
a.find(new Function());
a.find(tag`unicorn`);
a.find(this);

They could be function, but not very common. Some might need discuss. like fn() and fn1 || fn2.

• Fix some logic error in no-reduce rule.

Fixes #755

Do not merge, adding more. Done.
