On big-endian targets, the even elements are more significant than the odd elements and so should come second in the ZIP. This fixes many execution failures on aarch64_be-elf, including gcc.c-torture/execute/pr28982a.c. gcc/ PR target/118891 * config/aarch64/aarch64.cc (aarch64_expand_vector_init): Fix the ZIP1 operand order for big-endian targets.
