  Log Message:
  -----------
  [AArch64] Dont inline streaming fn into non-streaming caller (#150595)

Without this change, the following test would fail to compile
with `-march=armv8-a+sme`:

```
  void func1(const svuint32_t *in, svuint32_t *out) {
    [&]() __arm_streaming { *out = *in; }();
  }
```

But in general, it's probably better never to inline
streaming functions into non-streaming functions, because
they will have been marked as 'streaming' for a reason
by the user.
