arch-arm: Adapting IllegalExecution fault for AArch32

The Illegal Execution fault triggered by the setting of processor state
PSTATE.IL happens in AArch32 as well and takes the form of UNDEFINED
exception fault.  We are hence copying the UndefinedInstruction AArch32
fields into the IllegalInstSetStateFault.
