02e1a0f23c Merge lazy flags optimization by Darek Mihocka. 
I measure slight but consistent speedup of ~1-3% for all guests.
Tested: Windows XP/7 boot 32/64 bit, various Linux live CD

dfd769a102 - Fixed compilation issue with cpu-level=5 
- SYSCALL/SYSRET: SYSCALL/SYSRET instructions are not supported in legacy mode for Intel processors
- CPUID: CPUID.0x80000001.EDX[11] SYSCALL/SYSRET support should not be reported outside long64 mode if legacy mode SYSCALL/SYSRET is not supported
- Added new CPUDB entry - AMD K6-2 3D proc3essor (Chomper)

44241a1e56 - Added support for AVX and AVX2 instructions emulation, to enable configure 
with --enable-avx option. When compiled in, AVX still has to be enabled
    using .bochsrc CPUID option. AVX2 FMA instructions still not implemented.

  - Added support for Bit Manipulation Instructions (BMI) emulation. The BMI
    instructions support can be enabled using .bochsrc CPUID option.

371dc200fc Remove the 'trace' debug feature fro the main stream (which now runs with handlers chaining) and this way reduce each handler size. 
Another 3% speedup on WinXP boot on top of handlers chaining + reduction of Bochs binary size by 45K.
