c06b1e05ca [turbofan] Turn JSIntrinsicLowering into an AdvancedReducer.
This in turn allows usage of AdvancedReducer::ReplaceWithValue which
has access to the underlying graph reducer. It will allow us to deal
with exception continuations correctly.

d6e99a7f52 [turbofan] Introduce explicit JSCreateLiteral[Array|Object].
This uses explicit operators instead of intrinsic runtime calls to
create literals froms boilerplates. It allows for easier access of
static parameters and syncs it with other allocating operators.

4940c0bd42 [turbofan] Unify frame state inputs.
Now all nodes that care about deoptimization always take frame state
inputs no matter whether deoptimization is enabled for a particular
function. In case that deoptimization is off, the AstGraphBuilder just
inserts the empty frame state. This greatly simplifies the logic in
various places and makes testing easier as well, and is probably the
first step towards enabling --turbo-deoptimization by default.

There seems to be no noticable performance impact on asm.js programs.

Also fix the graph replay in order to regenerate the scheduler unittests.

d1597b7d22 [turbofan] Use FastCloneShallow[Array|Object]Stub if possible.
This allows the JSIntrinsicLowering to optimize the cloning of literal
boilerplate objects using either the FastCloneShallowArrayStub or the
FastCloneShallowObjectStub when applicable.

1592870822 Fixed the range information for string lengths.
Currently, this doesn't really help to generate better code,
nevertheless this is the right thing to do. When our type system(s)
are fixed, this should avoid falling back to floating point operations
in various cases.

677f3d5fd7 Added %_Likely/%_Unlikely intrinsics (special cases of GCC's __builin_expect).
Currently this only sets branch hints, so we get unlikely code "out of
the way", but in the long run the register allocator needs some love
to treat the unlikely code as, well, unlikely. :-)

4436c2642a [turbofan] Support for %_DoubleHi, %_DoubleLo and %_ConstructDouble.
This adds support for the double bits intrinsics to TurboFan, and is
a first step towards fast Math functions inlined into TurboFan code
or even compiled by themselves with TurboFan.

4f1597a92d [turbofan] Add new JSIntrinsicsLowering reducer.
The lowering of intrinsics is therefore now decoupled from the general
inlining logic.
