Change information

Commit message:
Add HeapProfiler::IsTakingSnapshot to public API

The function HeapProfiler::CopyNameForHeapSnapshot only works while V8
is taking a heap snapshot, but there is currently no way for the
embedder to tell whether a snapshot is in progress, so nobody can safely
use CopyNameForHeapSnapshot. To remedy the problem, this change adds a
function to check whether the heap profiler is taking a snapshot.
