    Avoid minimal language when DW_LANG_HIP is used.
    
    AMD clang is going to start using DW_LANG_HIP instead of
    DW_LANG_C_plus_plus_14 (see PR at
    https://github.com/llvm/llvm-project/pull/181738). Rather than
    falling back to the minimal language, this commit ensures that
    GDB will still treat it like a C++ app. The commit also adds
    a test to an existing one.
