qemu 0.12.0

    1: Correctness issues:
    2: 
    3: - some eflags manipulation incorrectly reset the bit 0x2.
    4: - SVM: test, cpu save/restore, SMM save/restore. 
    5: - x86_64: lcall/ljmp intel/amd differences ?
    6: - better code fetch (different exception handling + CS.limit support)
    7: - user/kernel PUSHL/POPL in helper.c
    8: - add missing cpuid tests
    9: - return UD exception if LOCK prefix incorrectly used
   10: - test ldt limit < 7 ?
   11: - fix some 16 bit sp push/pop overflow (pusha/popa, lcall lret)
   12: - full support of segment limit/rights 
   13: - full x87 exception support
   14: - improve x87 bit exactness (use bochs code ?)
   15: - DRx register support
   16: - CR0.AC emulation
   17: - SSE alignment checks
   18: - fix SSE min/max with nans
   19: 
   20: Optimizations/Features:
   21: 
   22: - add SVM nested paging support
   23: - add VMX support
   24: - add AVX support
   25: - add SSE5 support
   26: - fxsave/fxrstor AMD extensions
   27: - improve monitor/mwait support
   28: - faster EFLAGS update: consider SZAP, C, O can be updated separately
   29:   with a bit field in CC_OP and more state variables.
   30: - evaluate x87 stack pointer statically
   31: - find a way to avoid translating several time the same TB if CR0.TS
   32:   is set or not.
