[SSP] Accessing __stack_chk_guard when using LTO (#66535)

This is a pre-commit test of accessing the variable __stack_chk_guard
when the static relocation model is imposed on a module compiled with
pic enabled. It confirms issue
[#64999](https://github.com/llvm/llvm-project/issues/64999).

The intent is to update this test with the fix for the aforementioned
issue.
