* 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.
* g++.dg/inherit/virtual8.C: New test.
