80c35c6522 Always set the callee's context when calling a function from optimized code. 
This is necessary even for recursive calls because we're sharing optimized code among closures, which could call each other and have distinct contexts.

b008d99b11 Ensure that all descriptors have a valid enumeration index, and replace NextEnumIndex with LastAdded. 
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.

d7a5b7d5e2 Separating transitions from descriptors. 
In this design maps contain descriptor arrays, which in turn can contain transition arrays. If transitions are needed when no descriptor array is present, a descriptor array without real descriptors is inserted just so it can point at the transition array.

The transition array does not contain details about the field it transitions to. In order to weed out transitions to FIELDs from CONSTANT_FUNCTION (what used to be MAP_TRANSITION vs CONSTANT_TRANSITION), the transition needs to be followed and the details need to be looked up in the target map. CALLBACKS transitions are still easy to recognize since the transition targets are stored as an AccessorPair containing the maps, rather than the maps directly.

Currently AccessorPairs containing a transition and an accessor are shared between the descriptor array and the transition array. This simplifies lookup since we only have to look in one of both arrays. This will change in subsequent revisions, when descriptor arrays will become shared between multiple maps, since transitions cannot be shared.

one optimized code object per context. When allocating a new

that can be shared.

2fd1e1bbc2 Array index computation dehoisting. 
When an array index (in an array access) is a simple "expression + constant", just embed the constant in the array access operation so that the full index expression is (potentially) no longer used and its live range can be much shorter.
This is effective in conjunction with array bounds check removal (otherwise the index is anyway used in the check).

f46906d7a8 Reduce size of LIR instruction by one word and remove dead code. 
Until now we always recorded two deoptimization environments for instructions
that are marked as calls. We actually don't need two for all LIR
instructions except one (LInstanceOfKnownGlobal) where there is a lazy
deoptimization point in deferred code.

This change remove on of them and uses one virtual function instead
to make LInstanceOfKnownGlobal work as before.

Additionally, this change removes an unused predicate save_doubles_ from LIR
instructions and removes some helper functions that are used only in one place.

b0bb4f078a Fix assertion failure due to too many deoptimization ids. 
The failing mozilla test was caused by more deoptimizations
introduced by --always-opt and r11087.

We abort code generation in release mode, so we should do
the same in debug mode.

da03f56b1f Inline functions that use arguments object in f.apply(o, arguments) pattern. 
Support arguments materialization after deoptimization in all frames (not only in topmost one).

a8980079a0 Add flag --trace-phase to selectively produce IR trace output. 
By default --trace-hydrogen only generates the final IR (before
code generation). The other phases can be printed by specifying
them by their first letter. Currently H=HIR, L=LIR or Z=final IR (default)
are recognized.
