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.

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.

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.
