x86/Intel: don't accept malformed EXTRQ / INSERTQ
Operand swapping was mistakenly suppressed when the first two operands
were immediate ones, not taking into account overall operand count. This
way EXTRQ / INSERTQ would have been accepted also with kind-of-AT&T
operand order.
For the testcase being extended, in order to not move around "GAS
LISTING" expectations, suppress pagination.
