----------------
With @sdesmalen  we where thinking that maybe it is better to duplicate the run lines to have the BF16 intrinsics tested separately:

```
 RUN: %clang_cc1 -D__ARM_FEATURE_SVE  ... -target-feature +sve ...
 RUN: %clang_cc1 _DENABLE_BF16_TEST -D__ARM_FEATURE_SVE -D__ARM_FEATURE_BF16_SCALAR_ARITHMETIC -D__ARM_FEATURE_SVE_BF16 ... -target-feature +sve -target-feature +bf16 ... 
```

and wrap the BF16 tests in `#ifdef ENABLE_BF16_TEST ... #endif`.

this will make sure that the non BF16 tests will be erroneously associated to the BF16 flags.

Please apply these to all the run lines involving BF16 modified in this patch.
