34dee0319c Remove the typeof state threaded through the code generator. It was 
used to signal that an expression was the immediate subexpression of
typeof, or (?) in the arm of a conditional expression itself in the
typeof state.

It was inconsistently consulted.  It was not used for property loads,
but only for slot loads.  This means that we matched the Webkit JSC
(not Spidermonkey) behavior for:

typeof(true ? x : y)  // throws ReferenceError

and we matched the SpiderMonkey behavior (not JSC) for:

with ({}) { typeof(true ? x : y) }  // ==> "undefined"

Now we are expected to match the JSC behavior in all cases.

07cd399b5c Support for calls on named and keyed properties in the fast compiler of the form: 
o.x() and o[expr]()

other changes:
- Fix missing relocation info for StoreIC on global object.
- Generate only one common return sequence instead of always appending 
  "return <undefined>" at the end of each function: The first JS 
  return-statement will generate the common return sequence. All
  other return-statements will generate a unconditional branch to the common
  return sequence.

e82a07c0bd Simple toplevel code generator support for short-circuited boolean OR 
in a non-test (ie, value or effect) context.  (It is implicitly not in
a test context because the code generator does not support expressions
in a test context yet.)

Compilation is essentially the same as in the optimized code
generator.  The expression (e0 || e1) is compiled as if it were
(let (temp = e0) temp ? temp : e1).

On ia32 and x64 a single shared ToBoolean stub is used to convert a
value to a flag.  The inlined checks assumed by the stub are reordered
to compare to undefined (the common case in toplevel code?) first.  On
ARM a call to the runtime is used.  In the interest of code size no
checks are yet inlined on ARM.

fbc0eaa13d Added support for array literals to the toplevel compiler. They are 
currently compiled the same as with the optimizing compiler: they are
cloned from a boilerplate object and the boilerplate objects are
lazily constructed.

Also changed argument pushing on ARM to use stm (store multiple),
which required changing the order of arguments to the runtime
functions DeclareGlobals and NewClosure.  They were only used from
generated code.

Finally, changed the toplevel code generator so that stack pops to
discard a temporary became addition to the stack pointer on ia32 and
x64.

46e6297e3e Added infrastructure for optimizing new CanvasArray types in WebGL 
specification under development. The optimizations are patterned after
those previously done for CanvasPixelArray. This CL adds all of the
necessary framework but continues to use the generic KeyedLoadIC and
KeyedStoreIC code, to create a baseline for benchmarking purposes. The
next CL will add the optimized ICs to ic-ia32.cc and ic-x64.cc.

These new CanvasArray types have different semantics than
CanvasPixelArray; out-of-range values are clamped via C cast
semantics, which is cheaper than the clamping behavior specified by
CanvasPixelArray. Out-of-range indices raise exceptions instead of
being silently ignored.

As part of this work, pulled FloatingPointHelper::AllocateHeapNumber
up to MacroAssembler on ia32 and x64 platforms. Slightly refactored
KeyedLoadIC and KeyedStoreIC. Fixed encoding for fistp_d on x64 and
added a few more instructions that are needed for the new ICs. The
test cases in test-api.cc have been verified by hand to exercise all
of the generated code paths in the forthcoming specialized ICs.

586f94f292 Split the AST LoopStatement type into separate types for do/while, 
while, and for loops.

Previously they were distinguished by a type field, which required
runtime asserts to avoid invalid nodes (since not all loop types have
the same internal structure).  Now they C++ type system is used to
require well-formed loop ASTs.

Because they do not share compilation code, we had very large
functions in the code generators that merely did a runtime dispatch to
a specific implementation based on the type.

369214c159 Use a root array register for constant loads and stack guards on x64. 
This only wins us around 1% in performance, but it makes the code more

1656dd639a Fix regression caused by the generation of a shift stub during 
snapshot creation in a better way.

Encode whether or not the stub should use sse3 instructions in the
minor key of the stub.  The stubs generated during snapshot creation
will have sse3 disabled, but they will not be found when sse3 is
enabled.  Therefore they will only affect the code generated as part
of the snapshot.
