When a function is compiled to be in Streaming(-compatible) mode, full SVE
may not be available. This patch adds an interface to query that and
changes the codegen for FADDA (not legal in Streaming-SVE mode) to
instead be expanded for fixed-length vectors, or otherwise not to
code-generate for scalable vectors.
