44dfaa2a1e Fix test-cpu-profiler/FunctionCallSample flakiness under GC stress testing 
The test flakes on "V8 GC Stress" bots and the sample looks like this:
[Top down]:
   90     0   (root) [-1] #0 1
    1     1    (program) [-1] #0 2
   89    89    (garbage collector) [-1] #0 3
which means that almost all samples are inside GC and we have no |start| node in the collected profile.

Running the test with different combinations of --gc-interval=500 and --stress-compaction flags gives the results quoted below. They don't give a ground to require |start| node presense in the profile when doing GC stress testing. So this change makes the |start| node optional in the collected profile if GC stress testing is on.

559e1d4540 Correctly report stack trace when current function is FunctionApply builtin 
When pc is inside FunctionApply builtin function the top frame may be either
2) Internal stack frame created by FunctionApply itself.
In this case we know its caller's pc and can correctly resolve calling function.
1) Frame of the calling JavaScript function that invoked .apply(). In this case we have no practical reliable way to find out the caller's pc so we mark the caller's frame as 'unresolved'.

All this logic is implemented in ProfileGenerator. SafeStackFrameIterator is extended to provide type of the current top stack frame (iteration actually starts from the caller's frame as we know top function from pc).

e3f34a58b2 Reintroduce runtime zone to Isolate. 
In case tcmalloc is not being used, the malloc()/free() overhead
can be significant for several runtime functions like StringReplace.
Therefore we reintroduce the runtime_zone into Isolate and reenable
the segment caching functionality of Zone.

There's now also a simpler version of ZoneScope w/o nesting capabilities.

deoptimization, then treat the maps in the code as strong pointers.

Note that other optimized code in call stack must support deoptimization
because of the call instruction with side-effects.

4c5508b42f Correctly report callstack when current function is FunctionCall builtin 
When current function is FunctionCall builtin we have no reliable way to determine its caller function (in many cases the top of the sampled stack contains address of the caller but sometimes it does not). Instead of dropping the sample or its two top frames we simply mark the caller frame as '(unresolved function)'. It seems like a better approach that dropping whole sample as knowing the top function and the rest of the stack the user should be able to figure out what the caller was.

This change adds builtin id to CodeEntry objects. It will be used later to add similar top frame analysis for FunctionApply and probably other builtins.
