1. This policy was only used for unused spill operands. I'm assigning
an INVALID LOperand to those instead. As a result, we only need
3 bits to encode the policy and have one more available for virtual
registers.
2. Furthermore, corrected the calculation of the maximal number of virtual
registers and changed the upper limit for the size of the Hydrogen IR
accordingly.
3. Doubled the maximal number of deoptimization entries to 8K.

Replaced LookupResult::IsProperty by LookupResult::IsFound where possible.
...
Yak shaving for map sharing with accessor properties contd.: When CALLBACKS can
have map transitions, simply looking at the property type is not sufficient
anymore to decide if a property is there or not. One has to look at the actual
contents of the descriptor entry then, but this breaks down sometimes when the
lookup is being done with a NULL holder. Luckily enough, we can oftren replace
IsProperty by the simpler IsFound, because we inspect the type immediately
afterwards, anyway.

Refactored iterative map traversal.
...
The main goal is to cleanly separate between the several parts involved in the traversal:
* iterating over all transitions in a descriptor array
* iterating over all prototype transitions
* storing the parent and the current local traversal position in a map
* the iterative traversal algorithm itself
The previous algorithm for iterating over prototype transitions did a little bit too much here, iterating over the whole array instead only the filled part. This has been fixed on the way, too.
With this CL, it will be much easier to make the necessary changes to the descriptor array iterator to correctly handle map transitions for accessor properties. Furthermore, perhaps we represent transitions a bit different in the future, making finding them a bit easier. This would make some code in this CL (and elsewhere) quite a bit shorter and more efficient.

MIPS: Make sure transitioned arrays efficiently call builtin Array functions

Port r10356 (69da81).
Original commit message:
Loosen the requirement for Map equivalency on several map checks, including checks up the prototype chain, that are not sensitive to ElementsKinds. These selected map checks should also match against FAST_DOUBLE_ELEMENT and FAST_ELEMENT transitions of the original map. This specifically helps all variants of transitioned JSArrays to still efficiently call builtins like push, pop and sort.
