compilers: Make get_display_language a class or static method

Currently this is done at the instance level, but we need it at the
class level to allow compiler "lang" args to be gotten early enough.
This patch also removes a couple of instance of branch/leaf classes
providing their own implementation that is identical to the Compiler
version.
