Reserve first element in the Function's ic_data_array to hold the edge
counter array.
Until now we had a one-element array per edge counter. This reduces memory
used by edge counters.
This CL allows to optimize code without having to have the unoptimized
code present.
Also, save space in Instruction by making place_id_ and lifetime_position_
a union. place_id_ is exclusively needed by Load/StoreOptimizer,
lifetime_position by the FlowGraphAllocator.

I was able to convert 49 SNPrint(NULL, 0, ...) patterns to use the
macro. I had to use a #define for the format string 5 times due to
uses that didn't fit the macro.
2 occurences of SNPrint(NULL, 0, ...) had >=2 possibilities for the
format string based on runtime values, and I didn't try to convert
them.
Fixed ~10 format strings.

This enables thread-safe logging (e.g., ISL_Print, which will soon be renamed to THR_Print), which is needed for concurrent
marking (DetachCode) and compilation.
Make finalization of GC marking tasks concurrent, now that it's thread-safe.

indirectly by loading the target address from the code object).

Cache a pointer to the isolate's Heap in the Thread object
and use it in generated code for allocation.
Change generated allocation code to load allocation-top and
end via THR (THR->heap.top). This is slightly slower than
embedding the address, but faster than loading it
via the Isolate (THR->isolate->heap.top)

This allows to make the last explicitly named stubs shared between isolates.
When sharing code stubs, we can't do patching at their entry anymore.
Therefore, I had to remove patching support of the array allocation stub.
Is this a functionality we want to keep?
The change is mostly performance-neutral because optimized code has an inlined fast
path for array allocation and only uses the stub for the slow-case.
The only isolate-specific stubs left are object allocation stubs which are
associated with their Class are per-isolate.
Since this CL removes any isolate-specific stubs from StubCode, it becomes AllStatic.
