1361b8a866 HV: Enable the -O2 option for HV
Now the -O0 option is used. In such case the code is not optimized.

aa6c4e7666 HV: Initialize one variable to fix the compiling warning
If the optimization option is enabled, it is possible that one variable is 
not initialized before using in the get_vioapic_info. (In fact the warning is
bogus)
This is only to reduce the compiling warning.

fda00e6cd7 HV: Add gcc compiler option to disable FPU/SSE/MMX
FPU/SSE is not supported in HV. Otherwise it is possible that the
SSE/FPU register is used under -O2 option.
So the gcc option is added to disable them.

42bbc22ef2 HV: Use the CFLAGS to control the optimization option
Now two flags can be used to control the optimizatin option. So unify them
and only one flag can be used to config the optimization

7de42842d5 HV: Add one correct Descriptor_table struct to configure VMCS
Now one uint64_t type is used to obtain the corresponding descriptor_table
for GDT/IDT. This will cause the stack protect corruption under -O2.
So the descriptor_table struct is added to configure the GDT/IDT of VMCS.

V1->V2: Move the descriptor_table into vmx.h header file
And its type is renamed from dt_addr_t to descriptor_table.

52ca0fe8fc HV: Fix the incorrect operand-constraints for inline assembly
The RFLAGS will be touched in some inline assembly.(exec_vmxon/
RFLAGS_RESTORE). The "cc" constraint should be added. Otherwise
it won't be handled under -O2 option.
And "%%XXX" register should also be added into constraints.
Otherwise it will be optimized incorrectly.
