5baaf3c981 Use the HeapObjectIterator to scan-on-scavenge map pages. 
Deserializing the partial snapshot may prematurely stop using a map page, adding a free-space filler at the end. Scan-on-scavenge of map-space did not expect anything but maps, and would interpret the uninitialized memory as pointers. Using the heap iterator we can skip over free space and only visit maps.

ca16bb7ae2 Split out libplatform into a separate libary 
Also remove the "use default platform" compile flag. Instead, the embedder
has to provide the platform.

Change all binaries to use the default platfrom from libplatform.

Unless --job-based-sweeping is passed, nothing uses the platform yet, so
nothing will break for embedders (yet).

a1dd1a262c Revert "Remove special ExecutableAccessorInfo handling based on flag" 
Temporarily reverting until we figure out how to handle the API cases that use accessors to lazily compute values.
dataAttributeGetterCustom in V8MessageEventCustom (at least) overwrites itself with the computed value using ForceSet. We can either force such clients to first use ForceDelete before caching, use some other caching mechanism; or provide an API for lazily computed properties.
