Optimize the equality check case of ICCompare stubs.
...
This includes specialcasing the generation when we know that the maps
of the two objects are the same. In addition, a new specialized
compare ic known objects cache is created.
The reason for the cache is that we need to have access to the stub
code from the roots; if we do not, the GC will collect the stub. In
this specialized case we use the map pointer as key in the cache, and
we always do a lookup before generating code. Actually hitting
something in the cache will happen very rarely, but we could
potentially overwrite an existing stub, which again will lead to the
GC collecting this old stub (even if it is referenced from other code
objects)

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.

Sync parser and preparser on do-while and return statements.
...
This CL fixes the preparser to have the same liberal automatic semicolon
insertion behaviour as the parser. In the case of a return statement in
global code we throw a syntax error at runtime rather than an early error
due to compatibility with KJS. However that hack allowed the following
syntactically incorrect program in global code in the parser but not in
the preparser:
if (false) return else {}
while the slightly saner version with the obligatory semicolon
if (false) return; else {}
was disallowed in the parser, but the preparser allowed it. This CL also
fixes that issue.

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.

MIPS: Implement crankshaft support for nested object literals.
...
Port r10061 (c648e1d1)
Original commit message:
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.

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.

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.

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.

When scavenging update source slot before migrating object it points to.
...
Source slot might belong to a dead old object and we might allocate a new object over it when evacuating a new space object this slot points to. In this case if we update slot after migrating object we will write into migrated object.

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:

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.

Implement high promotion mode for new space.
...
This mode drastically decreases pause times by limiting maximum capacity
of the young generation when mutators generate many long-lived objects.
It shrinks new space back to the initial capacity and keeps it at that
capacity until survival rate decreases again.
