39c855bd48 Bailout from crankshaft if a global property is found in the prototype chain of the global object, not on the global object itself.

20f2c1c98a Make sure that we do not call is_extensible on the global proxy. 
When calling Object.isExtensible we did not do a check for the global
js proxy. This caused the check on the extensible bit on the map to
return true, even when the bit was set to false on the global js
object.

48fadffcc4 Fix bug in JSON.parse for objects containing "__proto__" as key. 
It added the __proto__ key as a normal key, which made it visible
in enumeration, while reading still hit the hard-coded accessor.

52cfd6ab16 Fixed a number of issues on x64 crankshaft port: 
- Don't use SmiSub when overflow can occur. It asserts that overflow
  does not happen.

- Actually use CompareICs and signal to crankshaft whether or not smi
  code was inlined.

- Fix bug in CmpI where 64 bits were compared instead of 32 bits.

- Implement Throw, DeferredStackCheck, StoreKeyedFastElement in
  lithium backend.

Revision 6635 added an assert on IA32 that there were no 'const' parameters.
This assert could be hit at compile time because we compiled the unreachable
body of functions with illegal redeclarations, which are thrown at runtime.

17da434b29 Remove instruction summaries. 
Instead of constructing a temporary container for all LOperands of each
instruction, the register works directly on the LIR instructions that
 provide an abstract interface for input/output/temp operands.

This saves allocation of zone memory and speeds up LIR construction,
but makes iterating over all uses in the register allocator slightly
more expensive because environment uses are stored in a linked list of
environments. We can fix this by using a flat representation of LOperands.

32cd13ebf1 Remove the redundant load on every context lookup. 
There was an unnecessary load on every statically-resolved context lookup.
Remove it.

This revealed a hidden bug in const initializers inside 'with'.  They claim
to be statically resolved (having slot type CONTEXT) but they occur in a
spot where the runtime context chain and the static scope chain do not
agree.  This is fixed by special casing const initializers in the backend.

I played with the repro page provided for the bug and found that GC
must be performed prior to taking a snapshot even if we only report
reachable objects. GC allows weak handles to finalize.  Now heap
profiler produces aligned results for the repro page in both modes.

25eb1a57c2 Add LICENSE.v8, LICENSE.strongtalk and LICENSE.valgrind to the v8 
directory to make it easy for embedders to reproduce the copyright
notice for binary redistribution.

Removed now obsolete strongtalk directory.

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.
