X87: Convert KeyedLoad indexed interceptor case to a Handler.
port r24042.
original commit message:
Convert KeyedLoad indexed interceptor case to a Handler.
Currently, KeyedLoads on objects with indexed interceptors are handled with a
special stub. Instead, key on the map and handler mechanism for more uniform
treatment.

Emit comment with instruction+reason before deopt calls.
Note that we still need to migrate from sometimes emitting those
comments by hand to passing a reason explicitly, but this can be done
incrementally in separate CLs.

Require V8 to be explicitly initialized before an Isolate is created
We also initialize the Isolate on creation.
This should allow for getting rid of the last remaining default isolate
traces. Also, it'll speed up several isolate related operations that no
longer require locks.
Embedders that relied on v8::Isolate to return an uninitialized Isolate
(so they can set ResourceConstraints for example, or set flags that
modify the way the isolate is created) should either do the setup before
creating the isolate, or use the recently added CreateParams to pass e.g.
ResourceConstraints.
