arch-arm: Add support for Tarmac trace-based simulation

A new InstTracer (TarmacParser) has been implemented. This tracer is
parsing a pre-existing Tarmac trace file [1] while gem5 is running; it
is comparing execution data together with trace data and it is dumping
differences.
This allows to use Tarmac format as a glue between heterogeneous
simuators speaking the same Tarmac language.

Kudos to Giacomo Gabrielli for writing the original tracer.
