    testsuite/arm: Add arm_v8_2a_fp16_neon and arm_v8_2a_bf16_neon options
    
    A few tests lack the dg-add-options directives associated with the
    dg-require-effective-target they are using. Adding them enables to
    pass the right float-abi option, and thus make the tests pass instead
    of emit an error.
    
    For instance, we now pass -mfloat-abi=softfp on arm-linux-gnueabi
    targets and the tests pass.
