Cachegrind: introduce special case for Ir

Because most Ir accesses touch only one line, and this
can be detected at instrumentation time, use a special
handler for that. This handler does not need to check
cache line crossing at runtime.

This does not change the results of the simulator at all,
but improves runtime by around 15% on perf benchmarks.
