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.

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.

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.

- In parser, check that all exports are defined.
- Move JSModule allocation from parser to scope resolution.
- Move JSModule linking from full codegen to scope resolution.
- Implement module accessors for exported value members.
- Allocate module contexts statically along with JSModules
(to allow static linking), but chain them when module literal is evaluated.
- Make module contexts' extension slot refer to resp. JSModule
(makes modules' ScopeInfo accessible from context).
- Some other tweaks to context handling in general.
- Make any code containing module literals (and thus embedding
static references to JSModules) non-cacheable.
This enables accessing module instance objects as expected.
Import declarations are a separate feature and do not work yet.
