1f28a3df07 Disable RunAllocate test case for turbofan unsupported platform. 
"RunAllocate" test case is added in d6945db7. it invokes Linkage::GetStubCallDescriptor

d6945db703 [turbofan] Add SimplifiedOperator::Allocate operator. 
This introduces a simplified allocation operator which can be used to
model inline allocations in TurboFan. It is currently used for context
allocations, but still disabled because change lowering introduces
floating allocations outside the effect chain that interfere.

a75e4cea8f [turbofan] Remove indirection in JSToBoolean/JSUnaryNot lowering. 
This reduces the overhead of typed lowering, because we lower
JSToBoolean/JSUnaryNot directly if possible, instead of first lowering
to AnyToBoolean, and then letting the SimplifiedOperatorReducer do the
further lowering.

Also remove some obsolete tests from the cctest suite that have since
been removed by proper unittests. And improve unitttest coverage for the
typed lowering cases.

155278d6f2 [turbofan] Skip write barriers when storing smi. 
On 64-bit targets, we can skip the write barrier for Store nodes if the
input is ChangeInt32ToTagged, because the value being stored is
definitely represented as a smi then.

d1b5aa0716 Removed most of the bogus CompilationInfo constructor calls. 
A CompilationInfo constructed from just an Isolate* and a Zone* is in
weird an inconsistent state (calling e.g. flags() on it will crash),
so we need to avoid them. This CL removes almost all of them, the
remaining 2 call sites in (for testing only) will be handled in a
separate CL. Things which have been changed:

  * Linkage is basically a decorator for CallDescriptor now.

  * ChangeLowering doesn't need Linkage at all.

  * JSGenericLowering doesn't need a full CompilationInfo*, just a
    single flag.

  * JSContextSpecializer doesn't need the full CompilationInfo, just a
    Context.

  * Removed unused CompilationInfo from SimplifiedLoweringTester.

This nicely decouples things already a bit more, but there's still
work to do...

b9886ae9ff Fix bugs in simplified lowering relating to int32/uint32 signs. 
Lowering of NumberToUint32 and NumberToInt32 was not correctly accounting for the sign of the input and the sign of the output, emitting the wrong representation changes.

Along the way, I've found cases where MachineOperatorBuilder would break if fed a machine type for loads or stores that was not cached, requiring MachineOperatorBuilder to take zone to allocate operators for these cases.

c7685a59f0 [turbofan] Use range types to type and lower arithmetic ops. 
This is based on Georg's work on typing arithmetic operations (https://codereview.chromium.org/658743002/).

Instead of weakening to bitset types, we weaken to the closest 2^n
limit if we see that we are re-typing a node with a range type (which
means that the node can be part of a cycle, so we might need
to speed up the fixpoint there).

0e16150d33 Better typing and type verification 
- Extend verifier to check types of JS and Simplified nodes.
- Untyped nodes now contain NULL as types, enforcing hard failure.
- Typer immediately installs itself as a decorator; remove explicit decorator installation.
- Decorator eagerly types all nodes that have typed inputs
  (subsumes typing of constant cache, removing its typing
  side-channel and various spurious dependencies on the typer).
- Cut down typer interface to prevent inconsistently typed graphs.
- Remove verification from start, since it caused too much trouble
  with semi-wellformed nodes.
- Fix a couple of bugs on the way that got uncovered.

To do: verifying machine operators. Also, various conditions in the
verifier are currently commented out, because they don't yet hold.

4ec63ff97e Reland 
- "Switch inlining to use simplified instead of machine loads."
- "Add copy support in inliner."

Reland fixes:
 - size_t conversion for 64bit arches
 - Don't call front() on empty vector
   (triggers assertion on windows)
 - turbo_inlining now implies turbo_types, as
   it requires simplified lowering.

496697df4e Add MachineSignature, which is an encapsulation of the machine types for parameters and return values in a graph. 
This utility will be used to simplify Linkage and fix representation inference
to work with graphs where parameters and return values are something other
than tagged. It will also make testing representation inference a lot
easier, since we can then exactly nail down the machine types of parameters
and returns.

This CL also adds c-signature.h, which demonstrates how to convert C function
signatures into MachineSignatures. The CSignatures will be used in tests to
make it easier and simpler to codegen tests.

90c8932596 Replace our homegrown ARRAY_SIZE() with Chrome's arraysize(). 
Our own ARRAY_SIZE() was pretty bad at error checking. If you use
arrasize() in a wrong way, the compiler will issue an error instead of
silently doing the wrong thing. The previous ARRAY_SIZE() macro is still
available as ARRAYSIZE_UNSAFE() similar to Chrome.

9803a72417 Unify MachineType and RepType. 
MachineType now tracks both the representation and the value type of machine quantities and is used uniformly throughout TurboFan.

These types can now express uint8, int8, uint16, and int16, i.e. signed and unsigned smallish integers. Note that currently only uint8 and uint16 are implemented in the TF backends.

670df5063b Implement representation selection as part of SimplifiedLowering. Representation selection also 
requires inserting explicit representation change nodes to be inserted in the graph. Such nodes
are pure, but also need to be lowered to machine operators. They need to be scheduled first, to
determine the control input for any branches inside.

This CL requires extensive testing. More tests to follow.
