Andreas Färber 0d6d1ab499 cpu: Avoid QOM casts for CPU() ... CPU address spaces touching load and store helpers as well as the movement of (almost) all fields from CPU_COMMON to CPUState have led to a noticeable increase of CPU() usage in "hot" paths for both TCG and KVM. While CPU()'s OBJECT_CHECK() might help detect development errors, i.e. in form of crashes due to QOM vs. non-QOM mismatches rather than QOM type mismatches, it is not really needed at runtime since mostly used in CPU-specific paths, coming from a target-specific CPU subtype. If that pointer is damaged, other errors are highly likely to occur elsewhere anyway. Keep the CPU() macro for a consistent developer experience and for flexibility to exchange its implementation, but turn it into a pure, unchecked C cast for now. Compare commit 6e42be7cd1.
