Bugfix: The general array constructor stub did not handle the case
...
properly when it is called with a function pointer in the type cell,
instead assuming that an AllocationSite object should be present. The
case where this can happen is if the cell is uninitialized, then the
first constructor call made is to the Array function of a different
context. In that case, we'll store the function pointer in the cell,
and then go ahead and call the array constructor stub too. The bug is
fixed by checking for the AllocationSite object map. If not found, the
constructor stub goes forward with a default ElementsKind, just as in
several other cases.
A test in allocation-site-info.js was beefed up to make sure the state
chain described above is traversed.

Add internal fields to JSArrayBufferViews (JSTypedArray and JSDataView)

information). This change adds those internal fields to JSTypedArray and
JSDataView, in a similiar way to how it is done for JSArrayBuffer.

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.

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).

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.
