To avoid a performance regression for context creation with snapshots, we avoid
creating a useless long map chain for regular expressions, keeping the snapshot
size almost the same as before.

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.

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).
