Heap profiler: perform a GC round before taking a snapshot
...
to get rid of global object loaded from a snapshot. This
eliminates the "double global object" issue. Thanks to Mads
for suggesting this!

Fix warnings on Win64.
...
Set warning level to /W3 and change implicit conversions from size_t
to int. Most "fixes" are simply manifesting the implicit casts or using
a special strlen replacement that returns int.

Add initial version of retainers heap profile.
...
The profile is taken together with constructors profile. In theory, it
should represent a complete heap graph. However, this takes a lot of memory,
so it is reduced to a more compact, but still useful form. Namely:
- objects are aggregated by their constructors, except for Array and Object
instances, that are too hetereogeneous;
- for Arrays and Objects, initially every instance is concerned, but then
they are grouped together based on their retainer graph paths similarity (e.g.
if two objects has the same retainer, they are considered equal);
