x86/insns: add VMGEXIT

cyrillos · cyrillos · commit e2ed7b7e125e · 2021-05-13T09:14:10.000+03:00
The instruction supports two forms with [f2] and [f3]. I guess we might add aliases as VMGEXIT2 and VMGEXIT3. For now simly leave a second form for ndisasm sake. https://bugzilla.nasm.us/show_bug.cgi?id=3392755 Signed-off-by: Cyrill Gorcunov <gorcunov@gmail.com>
