Fix gcc.target/aarch64/vec_zeroextend.c for big-endian
vec_zeroextend.c fails on big-endian as it assumes
0 index is the lower part but it is not for
big-endian case. This fixes the problem by
using the correct index for the lower part
for big-endian.
Committed as obvious after a test on aarch64_be-linux-gnu.
ChangeLog:
* gcc.target/aarch64/vec_zeroextend.c: Fix for big-endian.
