42595014a1 Fix issue with missing lock display. 
This was caused by a logic error concerning a lock state when thread t1
was waiting for a lock, thread t2 released the lock and thread t1 didn't
yet acquire a lock. High zoom level was needed.

(Threads are performing Wait, Obtain, Release operations on locks.)

           Problem

In the region marked by the problem line the lock count was 0, which
didn't trigger the appropriate code branch.

7424077d70 Store source location in a single object. 
Source file, function name and line number are now stored in a const
static container object. This has the following benefits:
- Slightly lighter profiling workload (3 instructions less).
- Profiling queue event size is significantly reduced, by 12 bytes. This
  has an effect on all queue event types.
- Source location grouping has now no cost, as it's performed at the
  compilation stage. This allows simplification of server code.
The downside is that the full source location resolution is now
performed in two steps, as the server has to query both source location
container and strings contained within. This has almost no real impact
on profiler operation.
