Dan Elphick 55a348ceb4 [explicit isolates] Remove various GetIsolates
Ran GetIsolate/GetHeap removal script over all the header files included
into objects.cc. Affected classes include: ScriptContextTable
RuntimeCallTimerScope GlobalDictionaryShape Map LookupIterator
PrototypeIterator FixedArrayBuilder

Manually fixed up Map to mark its write operations as safe for
GetIsolate since they modify the object as so can't be done in RO_SPACE.
