Instead, it is supposed to just return an empty context if it failed.
Also don't invoke interceptors (we don't for the parts that deserialize
from the snapshot anyways).

Creates an AstStringConstants container which pre-initializes the
string constants used by AstValueFactory. This ensures that all
AstValueFactories will produce the same AstValue objects for constants,
and so they can be used by the BytecodeGenerator without having to pass
the AstValueFactory to it, enabling construction off-thread.

KillFields of an object should remove its cache from all the fields.
Currently, the cache in the front field is kept which is not expected.
This patch fixes it.

1.
DCHECK in runtime-i18n.cc for case mapping was wrong to
assume that the longest primary language tag is 3 characters.
BCP 47 actually allows up to 8 characters.
2. GetFlatContent() was called to a string without flattening it first.

With this CL, context loads and stores are "strengthened" by reducing
the incoming context chain and decreasing the depth accordingly,
whenever possible. This enables more opportunities for specialization
and will let us easily add module context specialization later.

This puts lowering of {JSCreateClosure} operations behind a flag. For
now the benefit of inline allocating such closures is negligible, it
does increase code size, and breaks in combination with inlining based
on {SharedFunctionInfo}.

The simulator implements these exactly, but on ARM hardware,
the estimates are not exact, so CHECK_EQ will fail. This CL adds

Before, in `var p1 = p.then(() => {}) we would trigger the
before/after callbacks with p as the associated promise, but we must
call it with p1.
Also removes promise from PromiseReactionJobInfo.

This function was only needed for extrasUtils. Since it was simply
calling a builtin function, just expose that builtin instead. This
requires an arguments adapter frame for the builtin. As a drive-by
fix, also added an arguments adapter for the extrasUtils.resolvePromise
(and a regression test).
Other cleanup: removed unused native context slot for PROMISE_SET_AND_CREATE.
