acc4edead2 MIPS: Defer creating Handles for HConstants to the code generation phase.

65e7a14973 Handle setters on the prototype chain efficiently by default. 
Note that changes on the prototype chain should already be handled by
StubCompiler::CheckPrototypes, if not, it is a bug there and not in
LookupForWrite. Furthermore, neither test262 nor WebKit layout tests hint at a
compability issue, so it should be safe to remove a redundant check.

The good point about this CL: It improves Box2D's performance by 22%.

d51b6826dc 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.

b8a7abd1fc Perform HasFastProperties check on prototypes when computing call targets in Crankshaft, part 2. 
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.

2f43f5e9d7 MIPS: Rename "mips" arch to "mipsel" in the GYP build. 
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.
