2b730c2bf6 Don't exchange null and undefined with the global object in function.prototype.{call, apply} for natives. 
This makes us compatible with firefox in throwing an exception when
call is invoked on a builtin with null as the this argument.

4d1b2b1d38 Change the Hydrogen representation of uses. 
Rather than representing a use as a pointer to an HValue and then searching
for the specific (ambiguous) operand, we now represent a use as a pair of an
HValue and the input operand index.  Additionally, use a linked list instead
of a growable array list since we never use random access.

This allows us to remove a bunch of similarly named and subtly different
functions from the HValue API.  The cost in extra zone allocation per use is
partially offset by reusing use list nodes when replacing a use of one value
with another.

418501faef Refine allocation policy for input operands at calls. 
For instructions that are marked as calls we can use:

1. Fixed input registers

2. Use-at-start policy (register, memory or constant).

(Memory or constant would not need the use-at-start policy, but
not specifying use-at-start prevents the allocator from using
a register even if there is one available. That's why use-at-start
is required and guarded by assertion)

ea8312ba33 Reapply: Never use classic code generator. 
Crankshaft is now the default on all platforms. This is the first
patch on the way to removing the classic code generator from the
system.

This time with no removal of the crankshaft flag. --nocrankshaft is
not at all the same as --always-full-compiler which I had used instead
for testing. That was what caused timeouts on the buildbots because of
repeated attempts to optimize hot functions. It makes sense to keep
the crankshaft flag in case you want to run only with the full
compiler and with no adaptive compilation.

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.

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.

269b19b447 Crankshaft support for StringCharFromCode. 
This allows more efficient implementations of string keyed access,
String.prototype.chatAt, and String.fromCharCode.

9b311c21b1 Reduce strength of ModI for power-of-2 divisor. 
This is ia32 only. I will port it to other platforms if this looks good to you.

bc9ddf20bb ARM: Port r7089 to ARM 
Ensure that there is always enough bytes between consequtive calls in optimized code to write a call instruction at the return points without overlapping.

Add a call to deoptimize all functions after running tests with --stress-opt. This will catch some issues with functions which cannot be forcefully deoptimized. Some of the tests failed on ARM with that change without the rest of the changes in this change.

9cca7d2733 Combine typed and pixel arrays. 
Worth mentioning:
- Specialized versions of pixel array and store/loads inside the generic stubs have been removed, since to have parity for all external arrays, 8 different versions would have to be inlined/checked.
- There's a new constant in v8.h for external arrays with pixel array elements.

d31594feae Refactor construction of switch statements to avoid subgraphs. 
Refactor construction of switch statements so it doesn't use class
HSubgraph.

There are also a few improvements.  We do not use an auxiliary list of
comparisons because they're embedded as a linked list in the graph
under construction.  We share a common break block for all breaks from
the same switch.  We do not insert empty blocks unless necessary to
maintain edge-split form.

There is also a bug fix.  The entry to a clause body is a potential
join and must have a join ID set, otherwise deoptimization within the
body can go to an unpredictable place in the unoptimized code.

061fa8be11 Add the possibility for a code stub to be non-movable 
Non-moveable code-stube are allocated in large object space. They are only required on ARM where the different C-entry stubs are required to never move.

This gets rid of pre-computing these stubs and hope that they never move. Also for crankshaft the C-entry stub which saved doubles is not generated in the snapshot so it ends up being generated at runtime and potentially move.
