If the GL_ARB_shader_draw_parameters extension is enabled, we'll already have a gl_BaseVertex variable. It will have var->how_declared set to ir_var_declared_implicitly, and will appear in the program resource list.
If not, we make one for internal use. We don't want it to be listed in the program resource list, as the application won't be expecting it. Marking it hidden will properly exclude it.
