lost ability to run FreeBSD on bhyve on CURRENT

[Nikolai Lifanov]

Can someone look at Bugzilla  192470 please?
https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=192470

In short, for a few months now I couldn't boot FreeBSD in bhyve on one
of my systems, while booting Linux still works. I get "panic: CPU0 does
not support X87 or SSE: 1" when trying to run a 9.3 or 10.0 guest.

Host CPU information:

CPU: Intel(R) Xeon(R) CPU E31235 @ 3.20GHz (3200.09-MHz K8-class CPU)
  Origin="GenuineIntel"  Id=0x206a7  Family=0x6  Model=0x2a  Stepping=7

Features=0xbfebfbff<FPU,VME,DE,PSE,TSC,MSR,PAE,MCE,CX8,APIC,SEP,MTRR,PGE,MCA,C
MOV,PAT,PSE36,CLFLUSH,DTS,ACPI,MMX,FXSR,SSE,SSE2,SS,HTT,TM,PBE>

Features2=0x1fbae3ff<SSE3,PCLMULQDQ,DTES64,MON,DS_CPL,VMX,SMX,EST,TM2,SSSE3,CX16,xTPR,PDCM,PCID,SSE4.1,SSE4.2,x2APIC,POPCNT,TSCDLT,AESNI,XSAVE,OSXSAVE,AVX>
  AMD Features=0x28100800<SYSCALL,NX,RDTSCP,LM>
  AMD Features2=0x1<LAHF>
  VT-x: PAT,HLT,MTF,PAUSE,EPT,UG,VPID
  TSC: P-state invariant, performance statistics

It would be valuable to fix before 10.1 release, since 10-STABLE had an
up-to-date bhyve merged.

Thank you,
