  [flang][debug] Don't generate debug for compiler-generated variables (#112423)

Flang generates many globals to handle derived types. There was a check
in debug info to filter them based on the information that their names
start with a period. This changed since PR#104859 where 'X' is being
used instead of '.'.

This PR fixes this issue by also adding 'X' in that list. As user
variables gets lower cased by the NameUniquer, there is no risk that
those will be filtered out. I added a test for that to be sure.
