92bb77ef1d Merge patch from SF tracker: 
[3298173] Breakpoint on VMEXIT event by Jianan Hao

Patch description:

The patch provides a new command "vmexitbp" to set breakpoint when VM guest exit. The simulation will be stopped before first HOST mode instruction is executed.

Usage:
Type "vmexitbp" in debugger command window to switch it on/off (similar to modebp).


Currently, the patch has no corresponding interface on GUI debugger. Someone may add it if interested.

e6981218dc next step for fully configurable CPU + more optimal VMX execution 
- check at startup time which VMX fields are accessible
- next step: simplify VMREAD and VMWRITE instructions - eliminate switch statements
