Merge the constructor with the Initialize function below, assuming
create_heap_objects == true. This way, we only construct a nice, clean
initialized object.

   ASSERT(isolate == Isolate::Current());
-  memset(primary_, 0, sizeof(primary_[0]) * StubCache::kPrimaryTableSize);
-  memset(secondary_, 0, sizeof(secondary_[0]) * StubCache::kSecondaryTableSize);
 }
 
 
 void StubCache::Initialize(bool create_heap_objects) {
   ASSERT(IsPowerOf2(kPrimaryTableSize));
   ASSERT(IsPowerOf2(kSecondaryTableSize));
   if (create_heap_objects) {
     HandleScope scope;
     Code* empty = isolate_->builtins()->builtin(Builtins::kIllegal);
     for (int i = 0; i < kPrimaryTableSize; i++) {
