4fa7ae1c07 Optimize Object.seal and Object.preventExtensions 
They both now run fast (due to utilizing transitions instead of always
creating new maps) and sealed or non-extensible objects can stay in
fast mode after transitioning.

This almost entirely reuses the code for transitioning objects
frozen by Object.freeze(), with the added benefit of freeing
up a bit on the map (we no longer keep track of frozen-ness,
as that bit wasn't used for anything interesting).

9da4998204 Abort optimization in corner case. 
The %OptimizeFunctionOnNextCall sledgehammer can cause a function to be
marked for optimization before it's ever been compiled by fullcode.
This can lead to the situation where a function doesn't have optimization
disabled until we try to compile it optimized.

Basically, the assert should just handle this case more gracefully.

6ac4de87a8 harmony-scoping: make assignment to 'const' a late error. 
Per TC39 Nov 2014 decision.

This patch also changes behavior for "legacy const": assignments to sloppy const in strict mode is now also a type error. This fixes v8:2243 and also brings us in compliance with other engines re assignment to function names (see updated webkit test), but might have bigger implications.
That change can easily be reverted by changing Variable::IsSignallingAssignmentToConst.

The bug was an error when copying arrays in crankshaft. If it's a holey smi
array, the copy must be done as FAST_HOLEY_ELEMENTS to prevent representation
changes from being inserted that deopt on encountering the hole.

Also, prevent inlining array pop() and shift() if the length is read-only.
