f5c8ac9839 On ia32 LFunctionLiteral instruction should get context from esi register instead of stack slot. 
This makes LFunctionLiteral safe even when it is used from inside inlined function.

All other architectures were implementing LFunctionLiteral correctly.

b90a8ec851 Enable test-api/TurnOnAccessCheckAndRecompile and change it so it can't cause a GC. 
A GC in the access check callbacks NamedSecurityCallback and IndexedSecurityCallback
violates the contract about these callbacks.

Added a EXTERNAL VMState scope around the call to FailedAccessCheckCallback to be
consistent with the other callback invocations.

1336b913d0 Make built-ins strict mode conforming, and support a --use-strict flag. 
* Turned all uses of 'const' into 'var'.
* Turned all uses of local 'function' into 'var'.
* Added a couple of missing toplevel 'var' declarations.

One consequence is that the properties on the builtin object  are no longer
non-writable, and I had to adapt one test. Is that a problem?

Unfortunately, we cannot actually switch the library scripts to strict mode
by default, because that makes observable things like poisoned .caller properties
for library functions.

Also removed dead flag code in Compiler::Compile.

1dd2b094a5 Implement fast literal support in Crankshaft. 
This extends the current support for nested object literals we already
have in Crankshaft, to also support nested array literals and mixed
nested literals containing arrays and objects. All three types are
generated by the unified HFastLiteral instruction.

All previous upper bounds on nested literal graphs remain unchanged,
keeping the size of generated code in check.

The main intention is to boost performance of two-dimensional array
literals containing constant elements (aka. matrices).

bd79e299e5 Uniformly handle 'undefined' store to Float64Array and Float32Array. 
Previous behavior diverged in ICs and Crankshaft. When storing to a Float32Array or Float64Array, the ICs treated undefined as zero while Crankshaft treated it as NaN. Now both ICs and Crankshaft treat it as NaN, which is consistent with the WebGL & ECMAScript spec.

8a7f1568c4 Ensure that we do a non-incremental GC before relying on weak handle callbacks. 
Previously, some tests failed when being run with a low GC interval. This was
caused by a switch of the GC to incremental marking mode, which in turn did not
fire any callbacks for weak global handles. Now we make sure that we run in
non-incremental mode, although via a slightly misleading GC flag.

We should probably review the uses of PerformScavenge() and gc() in our tests to
see if they actually mean "make sure our callbacks fired".

b8b50400d2 Inline builtin Math functions functions in more cases. 
Until now we only could inline as specialized HIR instructions when called
as a method (e.g. Math.abs)

It is very common practice to abbreviate calls to those functions by defining
a global or local variable like:

var a = Math.abs;
var x = a(123);

This change allows inlining them when called as a function (global or local).

dc3f16a321 I will apply it to the nodes that can't be mapped to Heap object or Native object. 
As example there are 'Detached DOM Tree' nodes in WebKit. It is very useful to be able to see all such
nodes grouped together. It can be done with help of some post processing but I did this explicitly
on v8 side because it is much faster. At the moment this kind of nodes has kNative type.
I'd like to hide these nodes from the Retainment View but I can filter them only by name.

07d720ec41 Detailed heap snapshot usability improvement. 
The detailed heap snapshot has two groups of nodes. The first one
is the group for v8 heap nodes and the second one is the group for
native objects. At the moment we have two different sets of native
objects. There are 'Detached DOM trees' and 'Document DOM trees' type of objects.

I think it'd be nice to replace one group containing all native objects with
separate groups for different types of native objects.

The stub was directly patching caller's code without issuing write barrier which violated incremental marking invariants.

c4d3a110a2 Adjust position recorded for call expressions. 
For calls of the form ident(...) record position of the identifier as the position of the call. For other calls record positions of the opening parenthesis.

This guarantees that for expressions of the form function(){}() call position will not intersect with positions recorded for function literal which is used by the debugger for scope chain resolution.

81a0271004 Randomize the seed used for string hashing. This helps guard against 
CPU-eating DOS attacks against node.js servers.  Based on code from
Bert Belder.  This version only solves the issue for those that compile
V8 themselves or those that do not use snapshots.  A snapshot-based
precompiled V8 will still have predictable string hash codes.
