    tree: Hide wi::from_mpz from GENERATOR_FILE
    
    Similar to r0-85707-g34917a102a4e0c for PR35051, the uses
    of mpz_t should be guarded with "#ifndef GENERATOR_FILE".
    This patch is to fix it and avoid some possible build
    errors.
    
    gcc/ChangeLog:
    
            * tree.h (wi::from_mpz): Hide from GENERATOR_FILE.
