When CPUArchState* is available (here CPUX86State*), we can use the fast env_archcpu() macro to get ArchCPU* (here X86CPU*). The QOM cast X86_CPU() macro will be slower when building with --enable-qom-cast-debug. Pass CPUX86State* as argument to simulate_rdmsr / simulate_wrmsr instead of a CPUState* to avoid an extra cast.

OS X Hypervisor.framework support in QEMU
These sources (and ../hvf-all.c) are adapted from Veertu Inc's vdhh (Veertu Desktop Hosted Hypervisor) (last known location: https://github.com/veertuinc/vdhh) with some minor changes, the most significant of which were:
- Adapt to our current QEMU's
CPUStatestructure andaddress_space_rwAPI; many struct members have been moved around (emulated x86 state, xsave_buf) due to historical differences + QEMU needing to handle more emulation targets. - Removal of
apic_pageand hyperv-related functionality. - More relaxed use of
qemu_mutex_lock_iothread.
