fd6338bdda Implement assignment to undefined reference in ES5 Strict Mode.
Strict mode assignment to undefined reference.
Simple assignments (x = <value>) use CODE_TARGET_CONTEXT.
StoreIC stores its own strictness in extra_ic_state.
The strcitness is propagated as further ic stubs are generated.

Details:
* ReferenceError on assignment to non-resolvable reference in strict mode.
* Fix es5conform test expectation file.
* Add es5conform test suite into .gitignore.
* Fix Xcode project.
* Change implemented in virtual frame code generator, as well as full-codegen
  for all architectures.
* Fix debugger test.
* Fix comment for CODE_TARGET_CONTEXT
* Implement remaining StoreIC stubs to be strict mode aware.
* Trace extra_ic_state() for ic code stubs.

fed5622671 Better security checks when accessing named properties via Object.getOwnPropertyDescriptor.
Current approach returns undefined descriptor if caller is not granted v8::HAS_ACCESS.
If the caller has v8::HAS_ACCESS, for no JS accessors regular v8::GET_ACCESS check is
performed and value property of the descriptor is set to undefined if caller doesn't
have proper access.  For JS accessors both v8::GET_ACCESS and v8::SET_ACCESS are checked
and affect if getter and setter would be stored in the descriptor.

f1149734fc Partial fix for V8 issue 1079.
Record a safepoint with a deoptimization id for throw in optimized code.  We
don't seem to much care what the AST ID is because we will not be using it
for lazy deoptimization (throw doesn't return to the point of throw).  For
hygiene we use the actual ID of the throw expression.  Throw is no longer a
control-flow instruction, but it's followed by an unconditional abnormal
exit.  This is required to insert a simulate between the throw and the exit.

Make our optimized treatment of Function.prototype.apply act like a call and
have side effects.  This ensures that it will get a lazy deoptimization
environment.  Use that deoptimization ID in the safepoint for the call.

Deleting a property was also missing a deoptimization ID, though there was a
deoptimization environment assigned to the instruction.  Record the
environment and use the deoptimization ID at the safepoint.

93f8e3d821 Temporary disable comparison of optimizability of code objects in some cases.
With crankshaft, a code object can change its optimizability: it can start as
optimizable code object, but later we can find out it was a bad idea to
optimize it.  Alas, currently we don't have a proper event to communicate
this back to logger.  Hence we temporary allow a code object to be viewed
as optimizable judging from logs while being unoptimizable judging from
heap traversal.

cbc1c0fca6 Truncate rather than round to nearest when performing float-to-integer
conversions for external array types, which implement the Typed Array
spec. (Revision of http://codereview.chromium.org/6315004 .)

Prefer SSE2 code path on x86 processors. Non-SSE2 processors now make
a slow runtime call for float-to-int conversions. Use SSE3 for 32-bit
signed and unsigned int array types where possible.

The movement of code from ic-arm.cc to stub-cache-arm.cc caused the
VFP3 code path to be tested for the first time. Fixed bugs in the
register usage and in the constant value stored into integer arrays
for NaN and +/-Infinity.

Added new truncation test to test-api.cc. Storage of NaN and +/-Inf
was already covered. Ran unit tests on x86, x64 and ARM simulator.
Tested ia32 and x64 code in Chromium on Mac and Linux respectively
with Typed Array unit tests and WebGL content.

fae90d4f32 Make closures optimizable by Crankshaft compiler.
Currently only closures which only read from the context are supported.

ea7dde421e Unthread message handling test. Changing the MessageHandler in a
threaded test is not a good idea as it has an effect on other tests.

c1306244a6 Make the 'name' property on error prototypes read-only and dont-delete
to avoid leaking of error objects to accessor methods when formatting
error messages internally.

Also, do not call overwritten toString methods on error objects when
formatting messages internally.

8805509f28 Wrap external pointers more carefully.
On 32-bit platforms any pointer with 0 as LSB can be wrapped into Smi.  However, on 64-bit
platforms it's currently not the case as x64 Smis must have 0s in lower 32 bit word.
Even worse, macroassembler Move instruction will try to fetch integer value from Smi
and will shift by 32 bits to the right rendering stored pointer incorrect.

b4ea8c7f5e Enable sharding of individual testsuites in tools/test.py
This patch enables two new flags for the tools/test.py script;
--shard-count - giving the ability to split the tests to be run
into shard-count chunks.
--shard-run - giving the ability to specify which of the shards to actually run.

Example
  tools/test.py -j15 --shard-count=2 --shard-run=1 mozilla
would split the mozilla tests into two chunks and run the tests in the first chunk

Running:
  tools/test.py -j15 --shard-count=2 --shard-run=1 mozilla
  tools/test.py -j15 --shard-count=2 --shard-run=2 mozilla
is equivalent (in terms of test coverage) of just running:
  tools/test.py -j15 mozilla

In addition, tests are now sorted before they are returned from the
test specific ListTests methods (sputnik and mozilla tests where
already sorted before they where returned).

This change is needed to split a single test suite over two slaves on
the waterfall.
