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).

3d45e98b5e Remove %_SwapElements. This inlined runtime contained an optimization that was dangerous in the presence of incremental compaction. It also prevented QuickSort from array.js from being optimized by Crankshaft, so it is probably better to do without it. We have high hopes that this will fix bug=117879.

f9b93e6cc7 Implement map collection for incremental marking. 
This causes map transitions to be treated weakly during incremental
marking and hence allows clearing of non-live transitions. The marking
code is now shared between incremental and non-incremental mode.

4a7c70de23 Add zapping of Map contents in debug mode. 
This zaps the contents of stale descriptor arrays and prototype
transition arrays before overwriting references to them. It should help
to discover accidental sharing early and is needed for the heap verifier
when map collection with incremental marking lands.
