Problem Description:

The Linux kernel ACPI interpreter fails the following
AML test when it is compiled into a simulator. So if an
OEM BIOS includes this code, Linux would fail.

Steps to reproduce:

Run interpreter with the .asl demo code attached below.

ASL code to reproduce bug.

The Read access automatic dereference performs one dereference for
reference to object (but not object itself) passed to Method by argX
(no need to do DerefOf, though applying DerefOf provides the same
result as without it in this case).

In case a passed to Method reference is obtained by the
Index operation this feature doesn't work, but should.
Exception occurs instead.
