Subject: perf test: Add 'thloop' test workload

The thloop is similar to noploop but runs in two threads.  This is
needed to verify perf record --per-thread to handle multi-threaded
programs properly.

  $ perf test -w thloop

It also takes an optional argument to specify runtime in seconds
(default: 1).
