    testsuite: arm: bf16_vstn_1 vst3q_bf16 improved by late-combine
    
    The late-combine pass removes some unnecessary register copying in
    bf16_vstn_1.c, copying that was expected by vst3q_bf16.  Adjust the
    expectations so that they match the better code we get now.

            * gcc.target/arm/simd/bf16_vstn_1.c: Adjust expectations for
            code improved by late-combine.
