  -----------
  [Clang][AArch64] Warn when calling non/streaming about vector size difference (#79842)

The compiler doesn't know in advance if the streaming and non-streaming
vector-lengths are different, so it should be safe to give a warning
diagnostic to warn the user about possible undefined behaviour. If the
user knows the vector lengths are equal, they can disable the warning
separately.
