 - Adds support to the Arm assembler to use extended constant pools.
 - Update (set_)target_address_at to support extended constant pool load
   updates.
 - Replace Operand::is_single_instruction with Operand::instructions_required
   Due to the fact that different constant pool load types require different
   numbers of instructions.
 - Various cleanups of ConstantPoolBuilder to cleaner integration of the
   extended constant pool building.
 - Update GetRelocatedValue such that offsets to both map_check and bool_load
   are explicitly provided, rather than location of bool_load being inferred
   based on map_check, since the code inbetween is no longer of a predictable
   size.
 - Update MacroAssembler::GetRelocatedValueLocation() to add support for
   getting a value from an extended constant pool entry.
 - Update Debug::SetAfterBreakTarget() to use target_address_from_return_address
   when checking for debug breaks at constant pool load points.
 - Change ConstantPoolIterateBody to iterate over both heap and code pointer in
   the small section before moving onto the extended section, to work around the
   requirement of the serializer that pointers are iterated in-order.
 - Increase old_pointer_space SizeOfFirstPage() to offset the fact that constant
   pools are now in the old pointer space (rather than code).

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.

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).

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.
