Paolo Bonzini 43175fa96a target-i386: preserve FPU and MSR state on INIT 
Most MSRs, plus the FPU, MMX, MXCSR, XMM and YMM registers should not
be zeroed on INIT (Table 9-1 in the Intel SDM).  Copy them out of
CPUX86State and back in, instead of special casing env->pat.

The relevant fields are already consecutive except PAT and SMBASE.
However:

- KVM and Hyper-V MSRs should be reset because they include memory
locations written by the hypervisor.  These MSRs are moved together
at the end of the preserved area.

- SVM state can be moved out of the way since it is written by VMRUN.
