179aef2b8f VM initialization refactoring. 
This patch introduces global once per-process initialization and moves
the OS and CPU setup there. This makes CPU features isolate-independent.

cdf65ca087 Reimplement the padding of relocation information for lazy deoptimization on ia32. 
The previous implementation attempted to keep track of the needed
relocation size for deoptimization while generating the optimized
code. That was error prone. This patch moves the relocation resizing
to the deoptimizer as the last step of creating an optimized code
object.

The down side to this approach is that two relocation information byte
arrays are created for all optimized functions that do not have enough
relocation space for lazy deoptimization.

7d8e6c929d Enable GVN for polymorphic loads by not expanding them at the HIR level. 
This change adds a new IR instruction for polymorphic loads. It performs
map compares and loads in one IR instruction instead of splitting each
load into a graph of map-compares and field loads.
 
The advantage is a smaller IR and less basic blocks, plus it allows to
do GVN on polymorphic loads.

8066271fd2 Optimize calls to object literal properties that are initialized with a function literal. 
This allows fast calls and inlining of functions like:

var o = {f: function() { return "foo"; }}
o.f();


Object literals that contain function literals are initially created a dictionary mode
object and only transformed to fast properties once all properties are computed and
added. This allows us to create constant function properties for functions declared
inside the object literal. Function literals inside object literals are marked for
pretenuring so that they work as contant function properties.

Object literals without functions should just function as before.

c3172a6b7e Refactor polymorphic load and inline function graph construction. 
Change the way we construct the graph for polymorphic loads to match that of
polymorphic stores.

Introduce a stack-allocated helper for saving and restoring all the
function-specific graph builder state that needs to change when we begin
translating an inlined function.  Make this class authoritative by moving
redundant state out of the builder and deferring to the current function's
state.

Ensure that we always print a tracing message when abandoning an inlining
attempt.

The old version only added extra space when we did indirect calls, but
the problem remains the same with normal calls that can be represented
as a single byte. When doing patching each call will always be at
least 2 bytes long because we use RUNTIME_ENTY as the reloc mode.
