4e94cd8b08 Make arguments and caller always be null on native functions (fixes issue 1548 and issue 1643). 
With this change we follow Firefox, Safari has a slightly different approach where the property is just not there (at least according to GetOwnProperty).

ffc6c7e56b Introduce local function declarations in Crankshaft and fix issue 1647. 
We have to emit code for declarations later into the body block
(and not into the start block) so that the environment contains
the correct values.

In order to capture the environment effect of the declarations
that generate code (function declarations) I inserted a separate
AST id and a HSimulate after the declarations are visited.

Also fixes handling deopt in named function expressions:

b625ce2b6b Fix a bug in scope analysis. 
When recompiling code (e.g., when optimizing) we could incorrectly hoist
some function expressions.  This leads to incorrect results or a crash.  The
root cause was that functions were not correctly categorized as expression
or declaration at parse time.

This requires some extra hoops to prevent the print name "anonymous" for
functions created by 'new Function' from establishing a binding.

for the individually bound functions.

Our existing code will generate a new function on every call to bind,
but it will use the same shared function. When setting the lenght this
will be set on the shared function, i.e., the length of all bound
functions will be that of the last bound function.

4487f8c050 Revert "Revert "Fix a bug in scope analysis."" 
Reapply r8783 with an additional fix.

Because the preparser and parser do not use the same scope analysis to
determine if a function can be lazily compiled, the parser can have false
positives.  Rather than treating this as a parse error, treat the preparser
as authoritative and eagerly compile the function.

85f5afb717 Correctly mark functions from our natives files during compilation. 
When creating a CompilationInfo we always have the script and can
determine if it is a natives script.

Now that all natives functions are recognized as such, many of them
are called with undefined as the receiver. We have to use different
filtering for builtins functions when printing stack traces.

Also, fixed one call of CALL_NON_FUNCTION to be correctly marked as a
method call (with fixed receiver). Now that CALL_NON_FUNCTION is
marked as a native function this caused the receiver to be undefined.

0aa422923c Eagerly deoptimize on never-executed code-paths. 
If type-feedback indicates that an expression was never executed in
the non-optimized code, we insert a forced deoptimization right away
to enable re-optimization if we ever hit this path.

With this change we still continue to build the graph. As a next step, we
should remove the dead code after the deoptimize.

I had to remove one assert about the optimization status in a test since
we now immediately deoptimize after exiting the loop that triggers OSR.

Also remove a restriction that control-flow from an inlined function in a
test context always reaches both true- and false-target.

a01b45df58 Fix a number of tests that incorrectly used assertUnreachable. 
Our testing infrastructure uses exceptions to indicate
errors. assertUnreachable therefore throws an exception to indicate
that it was reached. Therefore, it cannot be used to check that an
exception was thrown using the pattern:

try {
  shouldThrow();
  assertUnreachable();
} catch(e) {
}

Such a test will always pass because assertUnreachable will throw an
exception if shouldThrow does not.

builtins file for arm and x64, plus a move of Array.prototype.toString
and Array.prototype.toLocaleString from should throw on null or
undefined to the non generic test cases in the function-call test (due
to us not currently supporting generic cases with these to functions)

2b730c2bf6 Don't exchange null and undefined with the global object in function.prototype.{call, apply} for natives. 
This makes us compatible with firefox in throwing an exception when
call is invoked on a builtin with null as the this argument.

1af840ad4c Be more discriminating about uses of the arguments object in optimized code. 
Because we track the value of the arguments object, we need to check
values whenever plugged into a forbidden value context.  It is not
enough to check at only variable references as we did previously.

7aec228dbb Cleanup of mjsunit.js code and make assertEquals more strict. 
Encapsulate the helper functions in mjsunit.js.
Now only exposes the exception class and the assertXXX functions.

Make assertEquals use === instead of ==.
This prevents a lot of possiblefalse positives in tests, and avoids
having to do assertTrue(expected === actual) when you need it.

Fixed some tests that were either buggy or assuming == test.
