Strictly speaking there are some left in api.cc, but they are in
deprecated functions with non-deprecated alternatives.
Apart from changes made using tooling, this also modifies
FieldType::AsClass to return Map* rather than Handle<Map> and converts
its call sites to create the Handle when they need it - currently
several sites immediately dereference the Handle.
Also marks WasmDebugInfo as NeverReadOnlySpaceObject so GetIsolate and
GetHeap remain usable.

Manually fixed up Map to mark its write operations as safe for

There is no good reason to have the meat of most objects' initialization
logic in heap.cc, all wrapped by the CALL_HEAP_FUNCTION macro. Instead,
this CL changes the protocol between Heap and Factory to be AllocateRaw,
and all object initialization work after (possibly retried) successful
raw allocation happens in the Factory.
This saves about 20KB of binary size on x64.

This no longer causes allocation, so it's safe to unhandlify.
This will allow us to use directly call into C++ (via CallCFunction)
to calculate the hash instead of going through the runtime (via
%GenericHash).

Previously, the only optimized code path for Maps and Sets was for String keys.
This was achieved through an implementation of various complex operations
in Hydrogen. This approach was neither scalable nor forward-compatible.
This patch adds the necessary intrinsics to implement Maps and Sets almost entirely
in JS. The added intrinsics are:
%_FixedArrayGet
%_FixedArraySet
%_TheHole
%_JSCollectionGetTable
%_StringGetRawHashField
With these additions, as well as a few changes to what's exposed as runtime functions,
most of the C++ code backing Maps and Sets is gone (including both runtime code in
objects.cc and Crankshaft in hydrogen.cc).
