a457040ca6 Ensure that non-optimized code objects are not flushed for inlined functions. 
Collector was flushing them if optimized code was reachable only through the stack (not through the JSFunction object) which happens when you have a pending lazy deoptimization.

Also prevent v8::Script::New from leaking internal objects allocated by the compiler into outer HandleScope.

08b4262512 Statically check for assignments to const in harmony mode. 
The ES.next draft rev 4 in section 11.13 reads:
It is a Syntax Error if the AssignmentExpression is contained in extended code
and the LeftHandSideExpression is an Identifier that does not statically resolve
to a declarative environment record binding or if the resolved binding is an
immutable binding.

This CL adds corresponding static checks for the immutable binding case.

The debugger preparation did not take optimized functions - including
inlined function into account. This caused the full-code used for
deoptimization to be the "lazy compile" builtin which did not work and

e26093f3d8 Make let/const outside of the extended mode early errors (under harmony flag). 
The ES.next drafts require that source code that matches the productions for
let and const bindings outside the extended mode trigger early syntax
errors. This CL adapts the parser / preparser accordingly under the harmony
scoping flag.

Summary:
* Harmony scoping flag not set: Old semantics allowing const in classic mode
with function level scope. Const binding in strict mode and let bindings in
classic and strict mode trigger early syntax errors.
* Harmony scoping is set: Use new harmony const and let in
extended mode and old const in classic mode. This is to preserve
compatibility with current web pages that already use
non-standard implementations of const. An early syntax error is
thrown on const in strict mode and on let in classic and strict
mode.

This depends on:

8866d63cc9 The ScopeIterator uses recorded scope position - as detailed in scopes.h - and 
source code positions it gets from the program counter to recreate the scope
chain by reparsing the function or program.

This CL includes the following changes
* Adds source code positions for the assignment added by the rewriter.
* Run the preparser over global code first.
* Use the ScopeType from the ScopeInfo to determine if the code being debugged
  is eval, function or global code instead of looking up the '.result' symbol.

1e9a7267ab Introduce extended mode. 
This CL introduces a third mode next to the non-strict
(henceforth called 'classic mode') and 'strict mode'
which is called 'extended mode' as in the current
ES.next specification drafts. The extended mode is based on
the 'strict mode' and adds new functionality to it. This
means that most of the semantics of these two modes
coincide.

The 'extended mode' is entered instead of the 'strict mode'
during parsing when using the 'strict mode' directive
"use strict" and when the the harmony-scoping flag is
active. This should be changed once it is fully specified how the 'extended mode' is entered.

This change introduces a new 3 valued enum LanguageMode
(see globals.h) corresponding to the modes which is mostly
used by the frontend code. This includes the following
components:
* (Pre)Parser
* Compiler
* SharedFunctionInfo, Scope and ScopeInfo
* runtime functions: StoreContextSlot,
  ResolvePossiblyDirectEval, InitializeVarGlobal,
  DeclareGlobals

The old enum StrictModeFlag is still used in the backend
when the distinction between the 'strict mode' and the 'extended mode' does not matter. This includes:
* SetProperty runtime function, Delete builtin
* StoreIC and KeyedStoreIC
* StubCache

8480569467 Fix lazy deoptimization at HInvokeFunction and enable target-recording call-function stub. 
Changes the way we do lazy deoptimization:

1. For side-effect instructions, we insert the lazy-deopt call at
the following LLazyBailout instruction.

     CALL
     GAP
     LAZY-BAILOUT ==> lazy-deopt-call

2. For other instructions (StackCheck) we insert it right after the
instruction since the deopt targets an earlier deoptimization environment.

   STACK-CHECK
   GAP ==> lazy-deopt-call

The pc of the lazy-deopt call that will be patched in is recorded in the
deoptimization input data. Each Lithium instruction can have 0..n safepoints.
All safepoints get the deoptimization index of the associated LAZY-BAILOUT
instruction. On lazy deoptimization we use the return-pc to find the safepoint.
The safepoint tells us the deoptimization index, which in turn finds us the
PC where to insert the lazy-deopt-call.

Additional changes:
 * RegExpLiteral marked it as having side-effects so that it 
   gets an explicitlazy-bailout instruction (instead of
   treating it specially like stack-checks)
 * Enable target recording CallFunctionStub to achieve
   more inlining on optimized code.

This implements block scoped 'const' declared variables in harmony mode. They
have a temporal dead zone semantics similar to 'let' bindings, i.e. accessing
uninitialized 'const' bindings in throws a ReferenceError.

As for 'let' bindings, the semantics of 'const' bindings in global scope is not
correctly implemented yet. Furthermore assignments to 'const's are silently
ignored. Another CL will introduce treatment of those assignments as early
errors.

This change is based on my previous change enabling inlining calls-as-function

As a result we could get a wrong value on top after deoptimization.

140ae348d2 Recognize special comparisons via pattern matching on the hydrogen graph, 2nd attempt. 
This time, we initially leave the HTypeof instruction in the Hydrogen graph,
even for the special cases. We later try to remove this instruction (and any
HConstant) in the canonicalization pass, if possible. Always removing the
HTypeof during the initial graph construction is wrong if e.g. it is used in an
HSimulate.

The removals can be generalized a bit, but this will happen in a separate CL.

de7b222e36 Support for precise stepping in functions compiled before debugging was started (step 2) 
This change will ensure that full code with debug break slots is compiled and activated for all functions which already have activation frames.

This additional handling is only for functions which have activations on the stack, and that activation is of the full code compiled without debug break slots. In that case the full code is recompiled with debug break slots. It is ensured that the full code is compiled generating the exact same instructions - except for the additional debug break slots - as before. The return address on the stack is then patched to continue execution in the new code.

Also fixed SortedListBSearch to actually use the passed comparision function.

bfd048173f Notify collector about lazily deoptimized code objects. 
All slots that were recorded on these objects during incremental marking should be ignored as they are no longer valid.

To filter such invalidated slots out during slots buffers iteration we set all markbits under the invalidated code object to 1 after the code space was swept and before slots buffers are processed.

Fix aggravating bug on X64 where assembler code used a value that was off

This change will ensure that all non-optimized code will be compiled
with debug break slots when debugging is initiated. This is handled by
scanning the heap for non-optimized functions without debug break slots and setting their code to be lazy recomplied. When the lazy recompilation happens the code will ge generated with debug break slots (if debugging is still active at that point in time).

2c8680cc46 Avoid size increase of snapshot. 
The prototype of builtin functions is already unwritable, so we don't
have to make it so (the default map for functions changes after builtins
are initialized).

We no longer need to make the prototype non-extensible, since all properties
that are ever read by the bultins code has been added and frozen already.
Adding properties to the prototype, or changing its __proto__, cannot affect
code.

Removing these two pieces of initialization code reduces the snapshot size
by a few Kb.

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.

ffa08197e4 tighten invariants of HValue::InferRange 
* src/hydrogen-instructions.cc (HValue::InferRange): Only mark values
  with int32 representation as never being -0.  Always return a non-NULL
  value; callers should check for representation().IsNone() if that's
  their concern.

  In practice these invariants were not violated by callers, but they
  were sometimes two calls away, which seems brittle.

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.

5c57d0d643 Remove support for logging into a memory buffer. 
The only usage of it was in logging tests, I've switched them for
using a file.

I've left out support for "--logfile=*" for now, as Chromium uses it.
Will be removed after the next V8 roll.

f4c4df2d9a Introduce scopes to keep track of catch blocks at compile time. 
The catch variable is bound in the catch scope.  For simplicity in this
initial implementation, it is always allocated even if unused and always
allocated to a catch context even if it doesn't escape.  The presence of
catch is no longer treated as a with.

In this change, care must be taken to distinguish between the scope where a
var declaration is hoisted to and the scope where the initialization occurs.

7d2be7c0e0 Support debugger inspection of locals in optimized frames 
Optimized frames are now handled by the debugger. When discovering optimized frames during stack inspection in the debugger they are "deoptimized" using the normal deoptimization code and the deoptimizer output information is used to provide frame information to the debugger.

Before this change the debugger reported each optimized frame as one frame no matter the number of inlined functuions that might have been called inside of it. Also all locals where reported as undefined. Locals can still be reposted as undefined when their value is not "known" by the optimized frame.

As the structures used to calculate the output frames when deoptimizing are not GC safe the information for the debugger is copied to another structure (DeoptimizedFrameInfo) which is registered with the global deoptimizer data and processed during GC.

We now only recognize "native function" when it occurs in extension scripts

Preparsing never recognizes native functions, which is acceptable since we
never preparse extension scripts (because we don't allow lazy functions
anyway).

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.

670f947a5c Implement set trap for proxies, and revamp class hierarchy in preparation: 
- Introduce a class JSReceiver, that is a common superclass of JSObject and
  JSProxy. Use JSReceiver where appropriate (probably lots of places that we
  still have to migrate, but we will find those later with proxy test suite).

- Move appropriate methods to JSReceiver class (SetProperty,
  GetPropertyAttribute, Get/SetPrototype, Lookup, and so on).

- Introduce new JSFunctionProxy subclass of JSProxy. Currently only a stub.

- Overhaul enum InstanceType:
  * Introduce FIRST/LAST_SPEC_OBJECT_TYPE that ranges over all types that
    represent JS objects, and use that consistently to check language types.
  * Rename FIRST/LAST_JS_OBJECT_TYPE and FIRST/LAST_FUNCTION_CLASS_TYPE
    to FIRST/LAST_[NON]CALLABLE_SPEC_OBJECT_TYPE for clarity.
  * Eliminate the overlap over JS_REGEXP_TYPE.
  * Also replace FIRST_JS_OBJECT with FIRST_JS_RECEIVER, but only use it where
    we exclusively talk about the internal representation type.
  * Insert JS_PROXY and JS_FUNCTION_PROXY in the appropriate places.

- Fix all checks concerning classification, especially for functions, to
  use the CALLABLE_SPEC_OBJECT range (that includes funciton proxies).

- Handle proxies in SetProperty (that was the easiest part :) ).

- A few simple test cases.

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.

Strict mode functions are to get 'undefined' as the receiver when
called with an implicit receiver. Modes are bad! It forces us to have
checks on all function calls.

This change attempts to limit the cost by passing information about
whether or not a call is with an implicit or explicit receiver in ecx
as part of the calling convention. The cost is setting ecx on all
calls and checking ecx on entry to strict mode functions.

Implicit/explicit receiver state has to be maintained by ICs. Various
stubs have to not clobber ecx or save and restore it.

CallFunction stub needs to check if the receiver is implicit when it
doesn't know from the context.
