    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.
