When the SME attributes tell that a function is or may be executed in Streaming SVE mode, we currently need to be conservative and disable _any_ vectorization (fixed or scalable) because the code-generator does not yet support generating streaming-compatible code. Scalable auto-vec will be gradually enabled in the future when we have confidence that the loop-vectorizer won't use any SVE or NEON instructions that are illegal in Streaming SVE mode.
