Bug 86488 – Web Inspector: use separate fields for storing HeapSnapshotLoaderProxy and HeapSnapshotProxy

• Component: Web Inspector (Deprecated)
• Status: RESOLVED FIXED

[Yury Semikhatsky]

Heap snapshot may be in 3 states: not loaded, loading and loaded. At the present time there is HeapProfileHeader._proxy field which may be either HeapSnapshotLoaderProxy or HeapSnapshotProxy which complicates the code a lot.

looks weird
