// in the interior of another function bypasses its s_set_vgpr_msb prefix, so
// the VGPR-MSB analysis must resolve the absolute target over the same surface
// the rewrite uses, mark the callee as entered at a non-start offset, and fail
// a mandatory WMMA split there closed rather than seed the wrong mode.
