svenpanne@chromium.org 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.
