Note expand used to do this for us:
/* If the constructor has fewer fields than the structure or
if we are initializing the structure to mostly zeros, clear
the whole structure first. Don't do this if TARGET is a
register whose mode size isn't equal to SIZE since
clear_storage can't handle this case. */-- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=18191
