When direct map, gpte_is_8_bytes has no meaning, but it is true for all
other cases except direct map when nonpaping.
Setting gpte_is_8_bytes to true when nonpaping can ensure that
!gpte_is_8_bytes means 32-bit gptes for shadow paging.
Then the right thing to do would be to rename it to has_4_byte_gptes and invert the direction. But as things stand,
it's a bit more confusing to make gpte_is_8_bytes=1 if there are no guest PTEs at all.
I will make the last 3 patches be a separated patchset and will do the rename.
