MIPS: Ensure that all descriptors have a valid enumeration index, and replace NextEnumIndex with LastAdded.

Port r12042 (ce65764e)

Original commit message:
The LastAdded points to the descriptor that was last added to the array. From the descriptor we can deduce the NextEnumerationIndex. This allows us to quickly find the property that we are transitioning to, which is necessary for transition-intensive code, eg JSON parsing.

The previous fix was for "real" calls, this one is for getters. It is a bit
unfortunate that this has to be fixed twice: We should really break up
Call::ComputeTarget into a predicate and 1 or 2 getters, so code can be reused.

The regression test has been modified a bit to make things more uniform.

In the traditional MIPS naming scheme, "mips" is used for
big-endian mips and "mipsel" is used for little-endian mips.
In V8 the "mips" build is little-endian, so the "mips" target is
renamed to "mipsel" to be compliant with the traditional MIPS
naming scheme.

This change is also required for supporting the Chromium project on MIPS.
