Reduce dependency on lodash functions: includes, uniq, repeat, isinteger (#11790) 
* Replace lodash 'includes' usage with Array.prototype.includes

* Replace lodash 'values' usage with Object.values

* Replace lodash 'uniq' usage with Array.from(new Set(...))

* Property safety: ensure that ignoreSuites/ignoreTasks are populated prior to access

* Revert "Replace lodash 'values' usage with Object.values"

This reverts commit 9fd3679d6db03066daee09fad0050e5292a32aa1.

Use for..of Object.keys instead of for..in (#9518) 
In https://github.com/babel/babel/issues/9511 (and #9495 is another symptom), @PavelKastornyy reported a node crash becaue the JavaScript heap run out of memory. The problem was that their code was adding enumerable properties to `Object.prototype`: it is something that shouldn't be done, but Babel shouldn't make node crash if someone adds them.
I reduced down the problem to `for...in` loops in `@babel/traverse` that grew the memory consumption exponentially because of that unexpected properties.

9a231c5671 Remove support for flow bindings (#6528) 
Flow bindings have been deprecated for a while.
The reason behind this change is that `declare var foo`
doesn't introduce a new local binding, but it represents
a global one.

3746273eda Path#ensureBlock keeps path context (#6337) 
* Path#ensureBlock keeps path context

This ensures that if you're inside an ArrowFunction with an expression body (say, you're on the BooleanLiteral in `() => true`), you don't suddenly lose your path context after inserting a variable.

This is because of 82d8aded8e (diff-9e0668ad44535be897b934e7077ecea5R14). Basically, an innocent `Scope#push` caused my visitor to suddenly stop working. Now, we mutate the Path so it's still in the tree.
