This patch should fix the tests by marking the appropriate variable 
volatile.
Sorry for the delay and breakage.
Ok for trunk?

Thanks,

    * gcc.target/aarch64/simd/vcaled_f64.c: Mark expected value volatile.
    * gcc.target/aarch64/simd/vcales_f32.c: Likewise.
    * gcc.target/aarch64/simd/vcaltd_f64.c: Likewise.
    * gcc.target/aarch64/simd/vcalts_f32.c: Likewise.
