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.
Flang Integration Tests
This directory can be used to add Integration tests involving multiple stages of the compiler (for eg. from Fortran to LLVM IR). It should not contain executable tests. We should only add tests here sparingly and only if there is no other way to test. Repeat this message in each test that is added to this directory and sub-directories.
