ClearNonLiveTransitions has to hold on to non-map values.
...
This ensures that we don't accidentally throw away getters and/or setters that are still needed. To make sure the bug gets triggered, we have to construct a situation where the map is on the live side of a live->non-live transition. This ensures that the map is passed to ClearNonLiveTransitions.

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.

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.

Make Error.prototype.name writable again, as required by the spec and the web.
...
Address http://code.google.com/p/chromium/issues/detail?id=69187 by instead
ignoring getters on ReferenceError.prototype.name in Error.prototype.toString.
And while we're at it, do the same for SyntaxError and TypeError, and the
properties "message", "type", and "arguments" on all of them, which
potentially have similar issues.

Bumped bootup memory limit on 32bit platforms using snapshot.
...
Somehow the mmaps we do look the same, but the info in the proc FS tells us that
we use a bit more memory. I am not sure if this is a real issue or not, but this
CL should at least get the build bots green again...
