4ca20a1d35 Simplify stack check instruction in Crankshaft.
So far we had two types of stack checks: one used for function entries
and one used at loop back edges which uses a deferred code object to
avoid spilling of registers in the loop.

After refactoring lazy deoptimization the first stack check can also
use deferred code. This change removes the first type of stack check
instruction in Crankshaft and uses a deferred stack check in all
places.

3c82957f04 Only make function literals in top-level object literals pretenured and constant function properties.
This change is a refinement of http://code.google.com/p/v8/source/detail?r=7283. Making all
function literals inside object literals constant function properties causes us to lose map
sharing. This hurts code where many object literals are created.

The idea is that top-level code is mostly executed once and functions inside top-level
object literals remain fast with this change.

e2f2c77e6f Be more willing to expand old space when evacuating new space at the end of
a mark-sweep.  We have a soft limit on old space size, which is designed to
trigger an old-space collection when we hit it.  Unfortunately although the
soft limit had already triggered an old space collection, the soft limit was
preventing objects from new space from being promoted.  For every promotion
candidate we were checking 3 different ways to allocate in old space before
giving up and putting the object in the other semispace.  This change allows
the promoted objects to go to old space and also makes us more eager to
sweep a page before trying other ways to find space for an object.

This shaves 416+ KB, just under 1% off the size of the debug d8 executable
on Linux (mostly because the CheckHelper functions for assertions were
getting separate copies for each compilation unit).  The difference in
release builds is negligible---a size reduction of 0.1%.

Also, change namespace-level 'static const' variables to remove the static
storage class as it's the default.

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:

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.

cbf08248f7 Make the parser track the language mode instead of keeping its own harmony flag.
So far the parser had its own harmony flag to disable the harmony scoping
feature when parsing native functions. With the introduction of the extended
language mode this becomes unnecessary because native functions will never enter
the extended mode. The parser can thus track FLAG_harmony_scoping and the
language mode of the current scope to see if harmony features are allowed. The
scanner and preparser have to keep their flag, because they can't use
FLAG_harmony_scoping as it is not available for the preparser-process
executable.

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

7e7d4dfd64 Implement crankshaft support for nested object literals.
This generates optimized code for deep-copying of nested object literal
boilerplates which are statically known. Most of the boilerplates have
already been generated at crankshaft time, so this optimization should
kick in for virtually every object literal. Only nested object literal
graphs up to a certain depth and containing up to a certain total number
of properties are considered for this optimization. This will prevent
explosion of code size due to large object literals (e.g. eval on JSON).
Improves splay performance because object literals are created often.

4c766c2330 Add histogram timer scope for preparsing.
Currently the parser benchmark doesn't count preparsing, since it doesn't
know when it's preparsing.
