This solves an issue with the custom startup snapshot, in cases where
deserializing the isolate requires more than one page per space.

This has the added benefit that these functions are now guaranteed not to throw when v8::Value::Is{Uint,Int}32() returned true, even when calling into JavaScript would throw a stack limit error.

Moved and renamed the scripts to fit with git.
These changes require documentation updates, updates of
the release spreadsheet and the buildbot side.

Currently the derived type of a right shift does not narrow the input
type based on the actual shift amount - well it does some narrowing
but more can be down. For patterns such as u32[i>>2], which is very
common is asm.js code, this limits the ability to later prove that an
index bounds check is unnecessary which can have a significant
performance impact.

This makes some internal renaming, e.g. trunk -> candidates,
bleeding edge -> master, without changing the api.
Also remove some unused bailout steps from the push script.
Remove unused bump version script.

Accessing the builtins object this way prevents sharing of code across
native contexts; instead we now load the builtin from the context of the
JS operation instead.

Along the way:
- Thread isolate parameter explicitly through code that used to
rely on getting it from the zone.
- Canonicalize the parameter position of isolate and zone for
affected code
- Change Hydrogen New<> instruction templates to automatically
pass isolate
