1bf18b8aae ! CPUID: Added TigerLake CPU definition (features CET and CLWB support) 
- CPU code refactor, remove uses of bx_bool datatype and use C++ classic bool instead.
  This enable better compiler optimizations and reduce binary size

13feb0772a - 10% emulation speedup with handlers chaining optimization implemented. The 
feature is enabled by default when configure with --enable-all-optimizations
    option, to disable handlers chaining speedups configure with
        --disable-handlers-chaining

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

892fa99c6f - prefetch hint should be NOP when use in register mode 
- #GP when trying to set reserved bits of CR4_HI in 64-bit mode
- #GP when trying to set reserved bits of EFER MSR
- clear upper part of RSI/RDI when executing rep instructions with 32-bit asize
  even if no repeat iterations were executed (because of RCX=0 for example)
- write SYSENTER_EIP_MSR and SYSENTER_ESP_MSR as 64-bit when x86_64 supported
- set MSR_FMASK reset value
- MSR_FMASK should be 32-bit only
- check for fetch permissions when doing ITLB lookup
- #GP when trying to write non-canonical address to MSR_CSTAR or MSR_LSTAR
- correct repeat instructions timing
- mark TSS busy in TR after it is loaded
