Call sequence logic that should be encapsulated in the Call and
CallFunction builtins. So the plan now is to switch Execution::Call
to accept any Callable and just pass that through to the Call builtin.

port 1e00bb57 (r30737).

original commit message:

    (reason for revert/reland: patch incorrectly left --vector-stores flag
     on, helpfully revealing some gcstress issues to look at, but they
     don't need to block this CL).

    Some pretty hacky code was used to carry out the tail-call
    handler dispatch on ia32 vector stores due to a lack
    of free registers. It really tanks performance. A better
    approach is to use a virtual register on the isolate.

port 54bab695 (r30747).

original commit message:

    Move the implementation of the Abstract Equality Comparison to the
    runtime and thereby remove the EQUALS dispatcher builtin. Also remove
    the various runtime entry points that were only used to support the
    EQUALS builtin.

    Now the Abstract Equality Comparison is also using the correct
    ToPrimitive implementation, which properly supports @@toPrimitive.

make it pass. We were not being diligent in maintaining top_on_previous_step_

Upon collection of the stack trace if the current PC falls into
the frame building code, the top frame might be in a non-consistent
state. That leads to some of the frames could be missing from the
stack trace.

The patch makes it check instructions under current PC and if they
look like the frame setup/destroy code, it skips the entire sample.

We already disallowed observing the global proxy; now we also
disallow any observation of access-checked objects (regardless
of whether the access check would succeed or fail, since there's
not a good way to tell the embedder what kind of access is being
requested).

Also disallow Object.getNotifier for the same reasons.

Defines a new --harmony-tolength flag, and a ToLengthFlagged() runtime function,
that is used where ES6 requires ToLength(), but a pre-ES6 conversion existed
before. When the flag is disabled, the function uses TO_UINT32(), which is
the pre-ES6 behaviour. When the flag enabled, the ES6-compliant ToLength()
conversion is used.

Implement the String constructor completely as native builtin,
avoiding the need to do gymnastics in JavaScript builtin to
properly detect the no argument case (which is different from
the undefined argument case) and also allowing to just
tailcall through to ToString or SymbolDescriptiveString for
the common case. Also the JavaScript builtin was misleading
since the case for construct call was unused, but could be
triggered in a wrong way once we support tail calls from
constructor functions.

This refactoring allows us to properly implement subclassing
for String builtins, once we have the correct initial_map on
derived classes (it's merely a matter of using NewTarget
instead of the target register now).

This introduces a new %SymbolDescriptiveString runtime
entry, which is also used by Symbol.toString() now.
