Suggestion: go-to-definition should go to a base definition if possible.

[ghost]

TypeScript Version: master

Code

class A {
    m() {}
}
class B extends A {
    m() {}
}

Expected behavior:

Go-to-definition on m in class B should go to m in class A. (Same if A were an interface.)

Actual behavior:

I get taken to the beginning of the current identifier.

If we do this, make sure this works if there are multiple implements clauses (some which do and some which don't declare m()) along with an extends
