Adds support for double-word aligned, i.e., 8 bytes on 32-bit platforms and 16 bytes on 64-bit platforms, objects in Oilpan. Changes: - Adds generic alignment APIs and overrides. - Internal logic to support double-word aligned allocations on LABs. - Adjusts natural alignment of large objects to follow double-word. - Adds a new static_assert() that suggests users file a bug if higher alignment is required. - Statically checks that no allocations with non-default alignment target custom spaces that support compaction.

Oilpan: C++ Garbage Collection
Oilpan is an open-source garbage collection library for C++ that can be used stand-alone or in collaboration with V8's JavaScript garbage collector.
Key properties
- Trace-based garbage collection;
- Precise on-heap memory layout;
- Conservative on-stack memory layout;
- Allows for collection with and without considering stack;
- Incremental and concurrent marking;
- Incremental and concurrent sweeping;
- Non-incremental and non-concurrent compaction for selected spaces;
See the Hello World example on how to get started using Oilpan to manage C++ code.
Oilpan follows V8's project organization, see e.g. on how we accept contributions and provide a stable API.
