5a3ec8532b Force eager compilation of some function literals. 
In case a function literal is followed by parenthesis, we consider this
a hint that it will be called immediately. If we happen to have parsed
that function literal eagerly, we can also compile it eagerly.

aaf403e92c MIPS: Swapped transition array and descriptor array. 
Port r12298 (7b39ef67)

Original commit message:
Now a map points to a transition array which contains the descriptor array. The descriptor array is now immutable. The next step is to share the descriptor array with all back-pointed maps as long as there is a single line of extension. Maps that require a descriptor array but don't need transitions will still need a pseudo-empty transition array to contain the descriptor array.

1ee6c0e30b Improved constructor inlining unit tests. 
Currently we inline functions with different contexts only on ia32, so we have
to move the helper functions for the various contexts to the top level. Further
more, "new Object()" seems to prevent inlining, too, so we us a simple object
literal.

Although things get consistently inlined now, something strange seems to happen
in test/effect contexts: The DEOPT output seems to contain too few frames, and
we don't get any DEOPT ouput after the first time for those contexts. This has
to be investigated...

a9f5f3d6f5 Fix the full compiler on ARM to always generate the same code 
regardless of the detected CPU.  This is a requirement for the
debugger and the deoptimizer, which both expect that code from
the snapshot (compiled without VFP and ARM7) should have the
same layout as code compiled later.

This is another change to make snapshots more robust with
arbitrary code.

f9aea9fcef Inline simple setter calls. 
Currently only simple setter calls are handled (i.e. no calls in count
operations or compound assignments), and deoptimization in the setter is not
handled at all. Because of the latter, we temporarily hide this feature behind
the --inline-accessors flag, just like inlining getters.

We now use an enum everywhere we depend on the handling of a return value,
passing around several boolean would be more confusing.

Made VisitReturnStatement and the final parts of TryInline more similar, so
matching them visually is a bit easier now.

Simplified the signature of AddLeaveInlined, the target of the HGoto can simply
be retrieved from the function state.

22e3c0ae04 Use the correct oracle in TestContext::BuildBranch. 
When inlining is being done, it is crucial to use the correct type feedback
oracle with a given type feedback ID. To ensure this, TestContext now carries an
oracle which is associated with the context's condition, and these are both used
together in TestContext::BuildBranch.

Note that in VisitReturnStatement and TryInline we are currently lucky that the
oracles don't go out of sync in an observable way, but this will change when we
inline setters. Therefore, there is no separate test case...

5deec59302 Unify handling of bailout IDs for property loads. 
Renamed Property::ReturnId to Property::LoadId, which describes its use more
accurately. Compound assignments and CountOperations now consistently use
Property::LoadId() instead of their own CompoundLoadId/CountId.

92f30d1df5 Improve load IC so it can call a native accessor even if the holder is 
in dictionary mode.  Add a flag to all maps to indicate whether they are
used for dictionary (normalized) objects or fast mode objects.

b5da7279b1 Introduced TypeFeedbackId and BailoutId types. 
This is a refactoring-only CL which improves the typing of IDs associated with
AST nodes. The interesting parts are in utils.h and ast.h, the rest of the CL
basically follows mechanically.

b49b32599b Make AdjustAmountOfExternalAllocatedMemory() more robust. 
Do not crash if called from a thread without V8 isolate, reset the external
memory counters in case of overflow, bump the external allocation limit.

This will allow us to track typed array allocation and deallocation in WebKit.
