[7.0] babel.util.arrayify and babel.util.canCompile are being removed

[loganfsmyth]

Currently babel/babel#5487 is proposing the removal of the whole babel.util object.

The extensions are now exposed at babel.DEFAULT_EXTENSIONS, canCompile was very simple, and extensions can just be splitting on a comma, so it should be a very easy update for 7.x.

I would lik to know how to upgrade to 7.0 for arrayify and babel.util.list? Thanks.

@shtse8 If you have a module that needs that behavior, you can certainly implement that logic yourself. It's just that Babel's core APIs have become stricter in what they expect.
