This is similar to -msve-vector-bits, but for streaming mode: it constrains the legal values of "vscale", allowing optimizations based on that constraint. This also fixes conversions between SVE vectors and fixed-width vectors in streaming functions with -msve-vector-bits and -msve-streaming-vector-bits. This rejects any use of arm_sve_vector_bits types in streaming functions; if it becomes relevant, we could add arm_sve_streaming_vector_bits types in the future. This doesn't touch the __ARM_FEATURE_SVE_BITS define.
