Handle all remaining statements nodes

They should all be handled already, organically. Adding a test for each of them should be enough.

• BreakStatement
• ClassDeclaration
• ContinueStatement
• DebuggerStatement
• DoWhileStatement
• ExpressionStatement
• ForInStatement
• ForOfStatement
• ForStatement
• FunctionDeclaration
• IfStatement
• LabeledStatement
• ReturnStatement
• SwitchStatement
• ThrowStatement
• TryStatement
• TSDeclareFunction
• TSEnumDeclaration
• TSExportAssignment
• TSImportEqualsDeclaration
• TSModuleDeclaration
• TSNamespaceExportDeclaration
• VariableDeclaration
• WhileStatement
• WithStatement

We should also ensure that the following statements are considered as non relevant:

• LabeledStatement
• TSModuleDeclaration (depending on body)
• TSNamespaceExportDeclaration

And make a decision about these ones:

• TSDeclareFunction
• TSEnumDeclaration
