c41cbe6d56 Link traces over taken branch optimization which makes handlers chaining even more efficient.
I observed 5% speedup in all disk images over 2.6pre1.
The change is safe (passed all regressions) and I will be glad to make it into Bochs 2.6!

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.

002c86660a reword all the CPU code in preparation for future CPU speedup implementation.
Bochs emulation can be another 10-15% faster using technique described in paper
"Fast Microcode Interpretation with Transactional Commit/Abort"
