    [torque] allow allocation of strings · 8ed9be48
    Tobias Tebbi authored
    This CL generalizes and improves how we handle allocations in Torque.
    
    Overview of the changes:
    - Remove obsolete special handling for JSObject classes, since it was
      incomplete: It breaks as soon as slack tracking is active.
    - Handle array initialization using slices.
    - Properly align allocation sizes. This enabled allocating strings.
    - Port AllocateSeq{One,Two}ByteString to Torque, which is much easier
      now than the old CSA code since allocation size alignment and
      large-object space allocation just happen out-of-the-box.
    - Remove obsolete or unnecessary intrinsics, some of them turn into
      macros in the torque_internal namespace.
    - Distinguish between header size and overall size for ClassType,
      make size optional and only defined when it is statically known.
