Philippe Mathieu-Daudé a9e445df54 target/i386/hvf: Use env_archcpu() in simulate_[rdmsr/wrmsr]() 
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:

  1. Adapt to our current QEMU's CPUState structure and address_space_rw API; many struct members have been moved around (emulated x86 state, xsave_buf) due to historical differences + QEMU needing to handle more emulation targets.
  2. Removal of apic_page and hyperv-related functionality.
  3. More relaxed use of qemu_mutex_lock_iothread.
