22bc8f6ac5 Alter the second hash used in StoreBuffer::Compact. 
hash2 >> (kHashMapLengthLog2 * 2) was always zero because hash2 was masked with (kHashMapLength - 1).

69366adfb6 Make sure transitioned arrays efficiently call builtin Array functions 
Loosen the requirement for Map equivalency on several map checks, including checks up the prototype chain, that are not sensitive to ElementsKinds. These selected map checks should also match against FAST_DOUBLE_ELEMENT and FAST_ELEMENT transitions of the original map. This specifically helps all variants of transitioned JSArrays to still efficiently call builtins like push, pop and sort.

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.

aae7033ba1 Fix JavaScript accessors on objects with interceptors. 
This fixes how Object.defineProperty() defines JavaScript accessors on
objects with installed API interceptors. The definition itself does not
cause any interceptors to be called, whereas any subsequent accesses on
said object will still fire the interceptor. This behavior is in sync
with API accessors.

04f0e33229 Fix handling of foreign callbacks in DefineOwnProperty. 
We use foreign callbacks to make some properties shadow internal values
but still behave as data properties from within JavaScript. This means
when a value is passed to Object.defineProperty() on such a property,
it should update the internal value instead of redefinind the property
and destroying the shadowing.
