95892799e1 Add access checks to Object.preventExtensions + add regression test for 1027. 
Object.preventExtensions can currently be used cross-domain. With this
change we follow firefox (IE9 has our current behaviour). In addition
this includes a regression test for 1027 and access tests for
Object.seal and Object.freeze.

6b4ff18b5b Properly process try/finally blocks. 
In some circumstances, try/finally block can actually catch the exception:

function f() {
  try {
    throw 42;
  } finally {
    return 0;
  }
}

Therefore when propagating exception to v8::TryCatch, we must be sure
there is no try/finally blocks as well.

When bulding the messages we should be more conservative and expect that
any v8::TryCatch with no JS try/catch in between can potentionally
be the right exception handler.

Plus various minor refactorings.

It made value of allowed_access_type[v8::ACCESS_KEYS] be a wild value.  On most of
platforms it was 0 and tests passed.  But on ARM (and on ia32 if you alter test a bit)
it could become true and hence allow enumeration of properties.

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.

d69ef26f7d Another fix for leaking error objects. User code can overwrite 
ReferenceError.prototype.__proto__ which will make "error instanceof
Error" fail. However, the ReferenceError.prototype object itself
cannot be modified. Therefore, the error checks must check for
concrete error instances instead of only checking for Error.

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.

On 32-bit platforms any pointer with 0 as LSB can be wrapped into Smi.  However, on 64-bit

Even worse, macroassembler Move instruction will try to fetch integer value from Smi

9673ee5d59 Get rid of requested size in RetryAfterGC. 
This was only used by Heap::CollectGarbage to check if after GC
available space is bigger than was requested, but nobody checked
the value returned by Heap::CollectGarbage, so requested size
was efficiently unused.

However, it may trigger spurious out of memory exceptions if requested
size is big enough.

7c238db829 Do not shortcut union of keys if lhs is empty. 
The problem is other array may have holes, for example
when fixed array comes from JSArray (in case of named interceptor).

If that would prove to be a performance problem, we could
pass an additional argument into UnionOfKeys to hold actual length.
