Per spec, accesses to a DataView object must throw a TypeError if
the underlying ArrayBuffer has been detached/neutered. Since that
implies a length of 0, we used to detect this as an out-of-bounds
access and throw a RangeError. Adding a separate check for buffer
detachedness lets us distinguish both cases properly.

Implements the change outlined in https://github.com/tc39/ecma262/pull/890,
which has been ratified and pulled into the specification. In particular,
template callsite objects are no longer kept in a global, eternal Map, but
are instead associated with their callsite, which can be collected. This
prevents a memory leak incurred by TaggedTemplate calls.
Changes, summarized:
- Remove the TemplateMap and TemplateMapShape objects, instead caching
template objects in the feedback vector.
- Remove the `hash` member of TemplateObjectDescriptor, and the Equals
method (used by TemplateMap)
- Add a new FeedbackSlotKind (kTemplateObject), which behaves similarly
to FeedbackSlotKind::kLiteral, but prevents eval caching. This ensures
that a new feedback vector is always created for eval() containing tagged
templates, even when the CompilationCache is used.
- GetTemplateObject bytecode now takes a feedback index, and only calls
into the runtime if the feedback is Smi::kZero (uninitialized).

A version of the spec change from
https://github.com/tc39/ecma262/pull/988, but applied to the
Async-from-Sync iterator type.
This change does not modify generated bytecode (but maybe it should to
take advantage of load IC feedback for loading "next"). Doing this grows
bytecode by quite a bit, since it's necessary to throw-if-not-an-object
before loading "next" (which currently gets to live in a code stub
instead).

https://github.com/tc39/ecma262/pull/988 gained concensus during the
september 2017 TC39 meetings. This moves the load of the "next" method
to the very beginning of the iteration protocol, rather than during
each iteration step.
This impacts:
- yield*
- for-of loops
- spread arguments
- array spreads
In the v8 implementation, this also affects async iteration versions of
these things (the sole exception being the Async-From-Sync iterator,
which requires a few more changes to work with this, likely done in a
followup patch).
This change introduces a new AST node, ResolvedProperty, which can be used
as a callee by Call nodes to produce the same bytecode as Property calls,
without observably re-loading the property. This is used in several
AST-desugarings involving the iteration protocol.
