Sander de Smalen 7e815dd76d [AArch64][SME] Create new interface for isSVEAvailable. ...

When a function is compiled to be in Streaming(-compatible) mode, the full
set of SVE instructions 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.
