... but why didn't it happen before? The problem seems to be that ix86_expand_vector_init_one_var is
creating an all-zero vector that isn't the same as CONST0_RTX, which is wrong, but the previous code did
the same thing and didn't get this problem.

No, Geoff, look closer at the failure message. The biggest problem is that
you deleted the line that converted a PARALLEL to a CONST_VECTOR node.
Testing a fix now.
