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.

Ensure that JSProxy::Fix gives the generated JSObject map a constructor

All JSObjects in V8 either have a map()->constructor() field or are
JSFunctions. JSProxy::Fix, however, was not enforcing this, and
Object.observe's use of JSObject::GetCreationContext() exposed this.

Note that this is not Object.observe-specific: the API call
v8::Object::CreationContext() also would have revealed this bug.

This patch chooses Object as a reasonable constructor to put on the
newly-fixed object's map. Note that this has no effect on the "constructor"
property in JS. In doing so, I've also tightened up the code underlying
JSProxy::Fix to only support JSObject and JSFunction as possible output
types.

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.

Fix memory leak. Make "V8 Linux - memcheck" build bot happy.

Flags::SetFlagsFromCommandLine allocates memory to hold copies of string
arguments when calling Flag::set_string_value(..., true) and presently
noone deallocates this. Resetting the flags will clear this memory.
Since Flags can be used throughout the entire V8 lifetime,
Dispose/Teardown seems like the right location to free this
memory.

This is rarely a problem in practice, but the memcheck buildbot (rightly)
complains.

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.
