f6017d36f2 Clean up d8 ArrayBuffer implementation and fix bug in readbuffer: 
- Separate CreateExternalArrayBuffer function.
- Properly create buffers for arrays constructed with size argument only.
- Finalization of data array is tied to buffer object exclusively.
- Get rid of hidden buffer reference in array objects and size header in data.
- Use 'new' instead of 'malloc' in readbuffer.
- Test cases for additional array and buffer properties.

e4c472a7af Implement correct checking for inherited readonliness on assignment. 
Removes 6 out of 8 of our remaining unintentional failures on test262.

Also fixes treatment of inherited setters added after the fact.

Specifically:

- In the runtime, when looking for setter callbacks in the prototype chain,
  also look for read-only properties. If one is found, reject (exception in
  strict mode). If a proxy is found, invoke proper trap.
  Note: this folds in the CanPut function from the spec and avoids an extra
  lookup over the prototype chain.

- In generated code for stores, insert a test for the maps from the prototype
  chain, but only up to the object where the property already exists (which
  may be the object itself).
  In Hydrogen, if the found property is read-only or not cacheable (e.g. a
  proxy), bail out; in a stub, generate an unconditional miss (to get an
  exception in strict mode).

- Add test cases and adapt existing test expectations.

ff216c9cea Re-land: Use map transitions when defining accessor properties. 
This is basically r11496, with the following changes:

 * Set back pointers in maps (cherry-picked from r11528)

 * Fixed size calculation in CopyInsert, as proposed by mstarzinger/rossberg

 * DefineFastAccessor uses GetCallbackObject instead of GetValue (for __proto__)

 * Put the code under a new flag, which is disabled by default

 * Cut down the corresponding regression test

 * Adapted bootup memory test, we actually only need a bit more memory on 64bit without snapshots, which can easily explained by more live maps lying around. Note that the snapshot variants are back to their previous limits.

Next steps: Investigate any performance degradationswith the flag enabled, and finally remove the flag when things are OK. Furthermore, GetCallbackObject should be merged into GetValue, the distinction is confusing and error-prone.

0260303568 MIPS: Array index computation dehoisting. 
Port r11596 (0cee9fca)

Original commit message:
Array index computation dehoisting.

When an array index (in an array access) is a simple "expression + constant", just embed the constant in the array access operation so that the full index expression is (potentially) no longer used and its live range can be much shorter.
This is effective in conjunction with array bounds check removal (otherwise the index is anyway used in the check).
