      [heap,snapshot] Replace first page size from snapshots with page trimming · ed8791ea
      mlippautz authored 
      Replace first page size in the snapshots with a heap logic that trims pages
after deserialization. The snapshot provided page sizes was just an
approximation, while the heap knows exactly where to trim.

Furthermore, trim the pages directly after deserialization, leaving no wiggle
room for further objects. This avoids pollution of the immortal immovable pages
with regular objects, e.g. Contexts. The downside is that we potentially require
expanding the space with a new page.

      Revert of [heap] Switch to 500k pages (patchset #24 id:780001 of https://codereview.chromium.org/2013713003/ )

Reason for revert:
Failures on waterfall:

e.g. http://build.chromium.org/p/client.v8/builders/V8%20Linux64%20TSAN/builds/11134

Original issue's description:
> [heap] Switch to 500k pages
>
> - Decrease regular heap object size to 300k, keeping the same ration (60%)
>   between this limit and page size.
>
> In a follow up, we can now get rid of the new space border page while
> keeping the 1M minimum new space size.
>
> Some results (v8.infinite_scroll; 3 runs):
> - evacuate.avg: +15.3% (1.4->1.2)
> - evacuate.max: +24.4% (2.4->1.8)

      [snapshot] revisit snapshot API. · 872c461b
      yangguo authored 
      This part of the snapshot API should not be in use yet, so we can still
change this. The motivation for this change is:
- Use MaybeHandle where reasonable.
- Remove ambiguity: when we use index to create context from snapshot,
  we should not have a silent fallback if snapshot is not available.
- Symmetry: rename to Context::FromSnapshot to mirror templates.

      [bootstrapper] no longer use outdated contexts list. · 564a2086
      yangguo authored 
      We currently use the outdated contexts list provided by the serializer
to update the receiver (the global proxy) in script contexts. However,
this is not actually necessary, since the global proxy is passed to the
deserializer and replaced as we deserialize.

Originally, the outdated contexts list is to update the global object
field in contexts. This was necessary since at the time the deserializer
creates the native context, the global object has not yet been created.
But the global proxy already exists.
