ChangeLog:
1. Refine codes in function vmx_run()
2. Fix bug of setting GUEST_RFLAGS
3. Move defines of selectors to lib/x86/vm.h
4. Move CR0/4 defines to lib/x86/vm.h, so as some defines in lib/x86/vm.c
5. Move some inline
be set in the
framework code.
Then I will wait for Paolo and Gleb's furthur feedback and commit the
final patch.

Hi Gleb,
It suddenly occured to me that this patch also fails to handle
GUEST_RFLAGS when VMRESUME.
I decide to remove rflags in struct regs since rflags can be read and
set via vmcs_read/vmcs_write in test suited

Change rflags in struct regs to host_rflags. Remove settings
to GUEST_RFLAGS since GUEST_RFLAGS can be set by vmwrite. Treat
host_rflags as host rflags before and after vmenter.
Besides, add checks to flags after vmenter.

Since Paolo's advice is a small change and this is only a test suite,
so I don't split these two and commit in one patch.
