This stages the general purpose inlining mechanism in TurboFan and
also disables the remaining tests that still fail. We do this to get
test coverage early and to avoid regressing inlining as we go along.

This fixes JSNativeContextSpecialization to not lower JSLoadGlobal and
JSStoreGlobal nodes if the global variable has morphed into a context
variable that is currently within a TDZ. Scary variable binding is being

parameter initializers are parsed in the enclosing scope,

This fixes the bailout point used by JSCreateScriptContext nodes for
top-level code. The bailout point differs from the Crankshaft one as
parameter slots have not been copied and the context chain was not
extended yet in TurboFan. Hence a new bailout id is required.

The debugger calls PromiseHasUserDefinedRejectHandler to recursively search the
tree of dependent promises for user-defined reject handlers. If no such reject
handler exists, rejecting the promise is considered an uncaught exception.

Promise.race and Promise.all interupt the link of promise dependency wrt the
search. This change fixes that link.

Re-land of https://crrev.com/cf13dda1ba25e8293ea143f33c6c5f6233a39c86,
fixing the issue with vector stores.

Class methods always have the class scope on their scope chain in order
to implement strong mode checks. Previously, that scope wasn't attached
to the ClassLiteral for anonymous classes (since the scope contained
no bindings).

This patch simply puts that same scope on the ClassLiteral, anonymous
or not, which simplifies other code that needs to reason about the scope
of a class and its methods.
