b1bd641078 Various minor cctest fixes to make ASAN a bit happier. 
* Running with ASAN needs more stack, so don't set resource constraints too
     tight.

   * Checking boot time memory usage doesn't make sense when running with ASAN,
     it eats tons of memory for itself.

   * Fixed a malloc/delete[] mismatch: Not surprisingly, the pointer wrapped by
     a SmartArrayPointer should better be allocated by, well, NewArray...

Even with these 3 fixes, we still have a few failures when running our test
suite with ASAN. Most of them are either timeouts or failures caused by greatly
increased stack usage.

69c2f54d32 Skip samples where top function's stack frame is not setup properly 
Stack iterator takes return address based on the frame pointer (ebp) and detects JS frames based on value at fp + StandardFrameConstants::kMarkerOffset. So in order the iterator to work correctly this values should be already setup for the current function. Stack frame is constructed at the very beginning of JS function code and destroyed before return. If sample is taken before before the frame construction is completed or after it was destroyed the stack iterator will wrongly think that FP points at the current functions frame base and will skip callers frame. To avoid this we mark code ranges where  stack frame doesn't exist and completely ignore such samples.

This fixes cctest/test-cpu-profiler/CollectCpuProfile flakiness.

8f602260d3 Implement yield* (delegating yield) 
Ideally this would have been implemented via desugaring at parse-time,
but yield* is an expression, and its desugaring includes statements like
while and try/catch.  We'd have to have BlockExpression in the AST to
support that, and it's not worth it for this feature.

So instead we implement all of the logic in
FullCodeGenerator::VisitYield.  Delegating yield AST nodes now have a
try handler index, for the try/catch.  Otherwise the implementation is
straightforward.

cfe3e039ca Don't use anonymous types declared in an anonymous union. 
They are a non-standard extension (probably in C1X, IIRC), but clang is unhappy
with them when -Wnested-anon-types is enabled, which seems to be implied by
-pedantic.

With this change and the previous fix for clang, we are now -Werror clean, even
on clang 3.3.

Previously, HDiv never had its CanOverflow flag cleared and HMod had
inverted logic (compared to HAdd, HSub and HMul). Minor cleanups on the way.

d97fe8d4df Add Persistent::ClearAndLeak. 
This will be relevant after Persistent is changed to Dispose itself when
destructed. With Persistent::ClearAndLeak, Blink can take the ownership of the
object pointed by a Persistent and avoid it getting destructed.

Casting NaN to int is unpredictable, on different architectures it produces different int value.

3f09e0a3d8 Remove separate maps for function instances 
ES3 specified that functions created via Function() would have
enumerable prototypes, unlike function literals.  For this reason, V8
has always had two prototypes for functions: "function_map" for
literals, and "function_instance_map" for "function instances": those
functions created by Function().

However, since 2009 or so, both maps have been the same!  Both have had
writable, non-enumerable prototypes.  Moreover, ES5 changed to specify
that function instances would have non-enumerable prototypes.

This patch removes the separate maps for function instances in sloppy
and strict mode.
