x86: Force strict ordering for memory mapped m5ops
Normal MMAPPED_IPR requests are allowed to execute speculatively under the
assumption that they have no side effects. The special case of m5ops that are
treated like MMAPPED_IPR should not be allowed to execute speculatively, since
they can have side-effects. Adding the STRICT_ORDER flag to these requests
blocks execution until the associated instruction hits the ROB head.
