arm64: Trace emulation of AArch32 legacy instructions
Introduce an event to trace the usage of emulated instructions. The
trace event is intended to help identify and encourage the migration
of legacy software using the emulation features.
Use this event to trace usage of swp and CP15 barrier emulation.
