    Support get_range_query with a nullptr argument
    
    get_range_query didn't support a nullptr argument
    before and would crash.

    https://inbox.sourceware.org/gcc/4f6718af-e17a-41ef-a886-f45e4ac3d7a4@redhat.com/T/
    
    OK? Bootstrapped and tested on x86_64-linux-gnu with no regressions.
    
    gcc/ChangeLog:
    
            * value-query.h (get_range_query): Return the global ranges
            for a nullptr func.
