Find Identifiers that are not part of a MemberExpression

[cpojer]

@fkling and I have both identified that this is useful.

What should the API be? We could do a filter:

j.find(j.Identifier).filter(j.identifierIsVariable)

or a find:

j.find(j.OurIdentifierType)

not sure about the naming though.

I think it should be a filter, then we can also use it in other occasions, for example in renameTo. There are also other situations where you want to ignore identifiers:

• Method/Function names
• Class names

Anything else?

Property names in ObjectExpressions:

{a: b} // don't rename a
{a} // rename a
