00e90b7e6e Remove deoptimization by patching the call stack. 
We go back to patching the code for lazy deoptimization because ICs need the on-stack return address to read/update the IC address/state.

The change also fixes bunch of tests, mostly by adding more deoptimization points.

(We still need to add code to ensure lazy deopt patching does not overwrite ICs and other lazy deopts; this is coming next.)

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.

6bbf6c5cb0 Schedule floating control. 
This CL makes several changes to the scheduling algorithm to handle control
flow that is not connected to End. Such control nodes constitute "floating
control islands" that must be linearized by the schedule. This is done
by considering such nodes to be schedulable, and then editing the control
dependencies after a first pass of scheduling. Then a subsequent pass of
scheduling will place all nodes correctly into the fully connected graph.

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.

d8295050d2 Fix deoptimization address patching in Turbofan to use safepoints. 
Since the deopt patch address needs to be available during GC to
resolve safepoints, we need to move it to the code object (instead of
the deoptimization input data) - accessing a separate fixed array
is not safe during GC. This CL adds a deoptimization_pc field to
each safepoint. The fields points to the deoptimization block.

The CL also fixes wrong register allocator constraints for
frame states on calls. These should always live on the stack
because registers are not preserved during a call.

1f776a07a6 Reland "More lazy deoptimization in Turbofan (binops, loads/stores)" 
This relands commit r23029 + adds missing lazy deopts for JSAdd operator inside VisitForInStatement. The added lazy deopt still refers to a bogus bailout id, but at least the graphs can be scheduled.

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.
