Add additional test cases for #1209

Browse Source 
These test cases don't use dynamic labels.
https://github.com/cc65/cc65/issues/1209#issuecomment-678738971

Also update the original test case for consistency:
* Change failure message to just "FAIL", as there is only one failure
* Outdent label definitions
* Clarify description
