Describe the bug
When developers conduct Extract Local Variable refactorings, CDT will sometimes not recommend a name for the developers, or the recommended names by CDT are not appropriate.

To Reproduce
Steps to reproduce the behavior:

1. Select an expression that needs to be extracted.
2. Click on 'Extract Local Variable' to conduct the refactoring
3. The popped dialog will be sometimes empty, i.e., without any recommended names.
4. Or the recommended names are inappropriate and low-quality.

Expected behavior
The popped dialog should contain at least one recommended name. To make things better, the recommended name should be appropriate in the current context, and descriptive enough to deliver the semantic meaning of the extracted expression.
