BuildGrowElementsCapacity bounds check used wrong elements kind.

BuildGrowElementsCapacity bounds check used wrong elements kind.

In a refactoring, HGraphBuilder::BuildGrowElementsCapacity() ended up
using the old_elements_kind instead of new_kind when calculating if a
new capacity for an array exceeds Page::kMaxRegularHeapObjectSize.

Repair, such that the check is correct.
