2014-12-11tools: Fix lcnt sort of inspected locksBjörn-Egil Dahlberg
An error was introduced in commit f24d1ad9004b2885cd3b15ac0bf9d1407ca68bc8 which reversed the sorting of all locks. This meant that the least contended locks was printed instead of the most contended. This commit reverses the reverse.

* egil/lcnt: Add test suite for lcnt in tools Add lcnt:rt_opt/1 bindings to erts_debug Add runtime option to enable/disable lcnt stats Add auto width on string output Add lcnt documentation Add lock profiling tool OTP-8424 Add lock profiling tool. The Lock profiling tool, lcnt, can make use of the internal lock statistics when the runtime system is built with this feature enabled. This provides a mechanism to examine potential lock bottlenecks within the runtime itself. - Add erts_debug:lock_counters({copy_save, bool()}). This option enables or disables statistics saving for destroyed processes and ets-tables. Enabling this might consume a lot of memory. - Add id-numbering for lock classes which is otherwise undefined.
