Log:
    PR c++/48035
    * init.c (build_zero_init_1): Extracted from build_zero_init.
    Add FIELD_SIZE argument, if non-NULL and field bit_position
    as not smaller than that, don't add that field's initializer.
    Pass DECL_SIZE as last argument to build_zero_init_1
    for DECL_FIELD_IS_BASE fields.
    (build_zero_init): Use build_zero_init_1.
