Inlining must be disabled when the call-site needs to toggle PSTATE.SM or
when the callee's function body is executed in a different streaming mode than
its caller. This is needed because function calls are the boundaries for
streaming mode changes.

More details about the SME attributes and design can be found
in D131562 <https://reviews.llvm.org/D131562>.
