    [clang][DebugInfo] Don't canonicalize names in template argument list for alias templates  

    **Summary**                                                                                

    This patch customizes the `CGDebugInfo` printing policy to stop canonicalizing             
    the template arugment list in `DW_AT_name` for alias templates. The motivation for         
    this is that we want to be able to use the `TypePrinter`s support for                      
    omitting defaulted template arguments when emitting `DW_AT_name`.                          

    For reference, GCC currently completely omits the template arguments                       
    when emitting alias template DIEs.                                                         

    **Testing**                                                                                

    * Added unit-test
