  [X86][AMX][NFC] Make comparison operators to be complete

The previous D101039 didn't fix the SmallSet insertion issue, due to we
always return false for the comparison between 2 different nonnull BBs.
This patch makes the the comparison to be complete by comparing `MBB`
first, so that we can always get the invariant order by a single
operator.
