btrace: Add support for interrupt events.
Newer Intel CPUs support recording asynchronous events in the PT trace.
Libipt also recently added support for decoding these.
This patch adds support for interrupt events, based on the existing aux
infrastructure. GDB can now display such events during the record
instruction-history and function-call-history commands.
Subsequent patches will add the rest of the events currently supported.
