If aarch64 supports target attribute/pragma, can't one function be target
("msve")
and another one not? Would something then register the builtins for the
functions that need it? And on the other side, if the builtins are already
registered because of some earlier "msve" function, something should ensure
there are no ICEs even in target ("mgeneral-regs-only") functions later.
